I will never forget Your precepts, for by them You have given me life. Psalm 119:93
Bible In One Year: Psalms 29-30; Acts 23:1-15
The young womans quest for God began when she was 11 years old, living under atheistic communism in the former Soviet Union. Thats when she saw some artwork that depicted the baby Jesus. When she heard that this represented what authorities called amythabout God sending His Son to earth, she began to seek the truth.
She also heard that God had written a book of His truth, and she searched for a copy. It wasnt until she was almost 30 that she finally found a Bible she was permitted to read. At last she had the information she needed to trust Jesus as Savior.
From 1971 to 1989, this young woman risked her own safety to search for the truth of Gods Word. Today she is a lawyer who works to protect her fellow Russian citizens from religious persecution. The message of Gods love in Christ is spreading because this one woman was a truth seeker.
Gods truth can have an impact on us and on the people with whom we interact. The psalmist wrote, Unless Your law had been my delight, I would then have perished in my affliction. . . . By them You have given me life(Psalm 119:92-93).
Lets make the Bible our delight. God will give us passion for His eternal Word if we are truth seekers. Dave Branon
If youre searching for nuggets of truth, the Bible is a gold mine.
Although the Flag Code does not specify a folding method, a tradition has developed over time. This method produces a triangular form like that of a three-corner hat and shows only the blue union.
Straighten out the flag to full length
Fold lengthwise once, then a second time to meet the open edge. Make sure that the union of stars on the blue field remains outward in full view. (A large flag may have to be folded lengthwise a third time.)
Then bring the striped corner of the folded edge to the open edge to form a triangular fold.
Turn the outer point inward parallel with the open edge to form a second triangle.
Continue the diagonal, or triangular, fold toward the blue union until the end is reached.
The folded flag should resemble a cocked (three-corner) hat, and only the blue union with stars should show.
If my memory serves,The USS Franklin was nearly lost at The Battle of leyte Gulf(Nov.1944).Once they got the fires out,she limped back to The Brooklyn Navy Yard.

The D4Y Suisei (Comet) was one of only two Japanese warplanes in service during the Pacific War to use a liquid-cooled inline engine as its powerplant. It was a nicely-designed plane, probably the most aesthetically pleasing single-engined bomber of the war. It was certainly the fastest carrier dive bomber of the war. It was of all-metal construction, but its career had some odd parallels with the Wooden Wonder, the British deHavilland Mosquito. Both were intended for the bombing role, but were first used operationally as reconnaissance aircraft. And both also served as night fighters. Unlike the Mosquito, however, the Judy, as the Allies code-named it, was not as big a success as it couldve been. Like most Japanese planes of its time, it lacked any protection for its two-man crew or for its on-board fuel. Although fast, it was still slower than the enemy fighters it was called upon to face, and was in fact often slaughtered in large numbers without compensating results to set against its losses. And although it could carry a heavier bombload than its predecessor, the Aichi D3A (Val) , it rarely did, despite the fact that, on two occasions when it did carry a heavier bombload, it scored its only major successes in its history-of which more later.
The Suisei was designed by the Naval Air Technical Arsenal at Yokosuka, hence its designation. It was created as a result of the success of the German Heinkel He-118, the fourth prototype of which had been purchased by Japan. The Navy had been impressed with this plane, an unsuccessful competitor of the Ju-87 Stuka, and had planned to produce it in a slightly modified form for carrier operation. But during a test flight, the He-118 had broken up in mid-air, ending that scheme. Still, the Navy thought that an inline-powered dive bomber was definitely in their future, so the Yokosuka Arsenal, late in 1938, was instructed to design a replacement for the Heinkel. The new aircraft was to be inspired by the He-118, but was to be smaller, faster, longer-ranged, and able to easily operate from any size aircraft carrier. A fully enclosed cockpit canopy was also part of the design criteria, as was an inward-retracting, wide-track landing gear. Chief Engineer Masao Yamana and his team created a clean mid-wing monoplane, comparatively small for a two-seat carrier dive bomber; although its wing was about the same size, in span and area, as that of Mitsubishis new A6M Zero fighter, the D4Y1 prototype could carry more internal fuel than the much larger Aichi D3A it was intended to supplant. The wing was so short, it precluded the need for any sort of wing-folding mechanism. It was not only smaller and lighter than its inspiration, the He-118, but it had an internal bomb-bay with a total load of 1,102 lbs., while the German plane had an external bomb rack, and could only carry the heavier bombload if the rear gunner was dispensed with. It was planned to power the D4Y1 prototype with an Aichi Atsuta engine (a license-built version of the DB-601A), but the new engine was not ready in time, so the first prototype took to the air for the first time in January 1941, powered by a 960 hp Daimler-Benz DB-600G, of which a few examples had been bought by Japan.
The performance and flight characteristics of the D4Y1 exceeded the Navys most sanguine hopes, and four more prototypes were quickly built by the Yokosuka Arsenal and joined the first in intensive testing. All of them were powered by the DB-600G and carried a defensive armament of two fuselage-mounted 7.7mm machine guns and one flexible 7.92mm gun (a copy of the German MG-15) in the rear cockpit. For short missions a total bombload of 1,234 lbs. could be carried, consisting of a single 1,102 lb. bomb in the bomb bay and two underwing 66 lb. bombs. But then came a near disaster: during simulated dive bombing tests, the wings began fluttering and stress cracks were afterwards found in the wing spars. Temporarily, at least, plans to have the Aichi Aircraft Co. Ltd. mass-produce the new bomber (as Yokosuka lacked the facilities to make it in more than prototype quantities) were shelved, as the D4Y1 was plainly not ready for operations in its design role.
Then, apparently, it occurred to someone that the D4Y1 could fulfill the carrier-borne reconnaissance role. The aircraft was plainly faster than the Nakajima B5N2 torpedo bomber, which was handling the carrier-borne recon mission at the time, and with drop tanks added, would have better range as well. So the D4Y1-C, or Navy Type 2 Carrier Reconnaissance Plane Model 11, was created. Powered by the 1,200 hp Aichi Atsuta 12 engine, it had the wing bomb racks beefed up and fitted with the necessary plumbing to carry a 72.6-gallon drop tank, and also mounted a K-8 camera in the aft fuselage. Two pre-production D4Y1-Cs went along to the fateful encounter at Midway, aboard the carrier Soryu, but both of them were lost when the carrier was sunk on June 4, 1942, and neither had a chance to prove the types worth. Still, the aircraft itself was perfectly good for the recon role, so it entered limited production in July while the Yokosuka team, aided by the engineers at Aichi, worked to improve the wing rigidity of the D4Y1. Only 25 production models were built by March 1943 because there was little requirement for a specialized carrier-based recon aircraft. But small detachments began serving aboard the larger Japanese aircraft carriers in the autumn of 1942, and the survivors remained in front-line service until the end of the Pacific War. The D4Y1-C was well liked by its crews, despite its lack of fuel and aircrew protection, but already ground crewmen were complaining that the Aichi Atsuta engine was temperamental and hard to maintain in service.
Meanwhile, development of the D4Y1 dive bomber continued; the main spars were reinforced, and the dive brakes improved, and the plane finally was accepted in March 1943, designated the Suisei Type 2 Carrier Bomber Model 11. As it was plain that the D3A was reaching the end of its career as a first-line aircraft, production of the Suisei was rapidly increased; most of the 589 examples built by Aichi between April 1943 and March 1944 were dive bombers. A few were designated D4Y1-KAI Model 21, as they were fitted with catapult gear to enable their operation from smaller carriers. But their carrier-borne debut in the Battle of the Philippine Sea in June 1944 was singularly inauspicious. Nearly all of the 141 Suiseis and 33 D4Y1-Cs embarked aboard the nine Japanese carriers in that battle were lost, most of them in the first days air battles, immortalized under the name, The Great Marianas Turkey Shoot.
Lieutenant (jg) Alexander Vraciu was one of the American Navy fighter pilots in that battle. Already an ace with 12 kills, he thought hed missed the best of the action because his engine was running roughly and wouldnt produce full power at altitude. But after circling for a while with other fighters with similar problems, he was vectored by the fighter director aboard his carrier, the Lexington, toward a large formation of approaching planes, and as other pilots warded off the Zero escorts, Vraciu joined twelve other Hellcats in attacking the enormous gaggle. In just eight minutes, Lt. Vraciu added six Judys to his score. That his engine was not operating smoothly didnt matter when pursuing and destroying enemy dive bombers weighted down by bombs. He made pass after pass at his opponents; he was rewarded by the sight of Judy after Judy exploding in flames and falling away burning in a last fatal dive for the sea below. Vraciu was an outstanding shot; he fired just 360 rounds during this fight-an average of only 60 rounds per kill. Rarely had a Japanese planes vulnerability to fire been demonstrated so conclusively. Vraciu was awarded the Navy Cross for this feat; a Zero shot down the next day raised his score to 19, a record that lasted for the next four months.
Despite the clear and ominous lesson of the Marianas Turkey Shoot, the next Judy variant still had no provision for crew or fuel-tank protection! The Suisei Type 2 Model 12, or D4Y2, entered production that April, but none were available in time for the Philippine Sea battle (perhaps, considering the enormity of the disaster, its just as well). This version was powered by the improved Atsuta 32 engine of 1,400 horsepower. The D4Y2a differed only in having a 13.2mm machine gun in place of the former 7.92mm gun in the rear cockpit. When fitted with catapult gear their designations were D4Y2-KAI Model 22 and D4Y2a-KAI Model 22a, respectively. A few of both kinds-the exact numbers are not available-were completed as D4Y2-C and D4Y2-Ca recon planes. These all saw their first combat in the air battles off Formosa and in the Battle for Leyte Gulf; most of them were destroyed by the superior numbers of Hellcats defending the American carriers, others being expended in kamikaze attacks, but one land-based Judy did get very lucky and dropped a single 1,102-lb. bomb on the light carrier Princeton-right in the middle of fighters and bombers preparing to take off and attack the Japanese surface fleet in the Sibuyan Sea. Amazingly, this solitary bomb in the wrong place at the wrong time was enough to devastate the gallant little ship; she was scuttled as evening drew on. The Princeton remains to this day the only first-line aircraft carrier of any nation sunk by a land-based air attack-ironically enough, by a naval dive-bomber.
In the meantime, production of the Atsuta-powered Suisei had ceased. The Atsuta engine was clearly a maintenance headache under even the best of conditions, and since an inline engine also powered the Armys Ki-61 fighter, concern over the availability of radiator coolant entered the equation, as well. Many members of the Naval Air Staff advocated the replacement of the unreliable Atsuta with an air-cooled radial engine of similar power output as early as the turn of 1943-44. The Suiseis slim fuselage seemed to preclude such a switch, but Aichi studied the problem, even examining an imported Focke-Wulf 190 for practical inspiration. By May 1944 a prototype was ready; it was powered by a 1,560 hp Mitsubishi Kinsei 62 fourteen-cylinder radial in a beautifully streamlined cowling. Tests showed that the new variants performance in nearly all respects matched that of the Atsuta-powered D4Y2, and the only negative qualities in the modification were a reduction in the pilots forward visibility during carrier landings and while taxiing on land. The Navy was satisfied, though, particularly with the Kinseis greater reliability, so they ordered the new variant from Aichi as the D4Y3 Suisei Carrier Bomber Model 33. There was also a D4Y3a model, similarly armed as per the D4Y2a. Late production D4Y3s were fitted with rocket-assisted take-off gear under the fuselage, for maximum-weight launching from smaller carriers, but no reconnaissance version of this subtype was built, as the Nakajima C6N had become available to assume this role.
It was a D4Y3 which accomplished the only other major success for the Judy, other than the destruction of Princeton; on March 19, 1945, while only 60 miles off Japans coast, the Essex-class carrier USS Franklin was bombed by a D4Y3 which planted two 551-lb. bombs on her crowded flight deck. The Franklin turned into a raging inferno, and only the excellence of American damage-control techniques and equipment, plus her crews determination, saved the ship from either sinking or being scuttled. She eventually made it back to the Brooklyn Navy Yard, an epic 12,000-mile voyage, but her career as a carrier was over.
Several Suiseis had, in the meantime, been expended as kamikaze suicide attackers, and so the Navy decided that the next production D4Y would be built especially for suicide attack. The D4Y4 Suisei Special Attack Bomber Model 43 was designed as a single-seater, as it was felt that a rear gunner was not needed for a one-way trip. This subtype carried a single 1,764-lb. bomb semi-recessed beneath the fuselage, and RATO auxiliary rockets were installed to either shorten the take-off run from small airstrips, or add speed during the final attack dive. Two hundred and ninety-six were built in 1945 by Aichi.
The Navys 11th Air Arsenal at Hiro also built small numbers of Suiseis; between April 1944 and the final collapse, this maker delivered 215 D4Y1s, 2s, and 3s. It also modified a small number of D4Y2s as expedient night fighters. For this mission, all carrier equipment, the underwing racks, and the flexible rear gun were removed, the bomb bay was faired over, and a single 20mm cannon was mounted obliquely in the fuselage, firing forward and upward at a 30-degree angle. A few also received racks for underwing air-to-air unguided rockets. Designated D4Y2-S, or Suisei-E Night Fighter, it saw only limited success against night-raiding B-29s, as it utterly lacked air-interception (AI) radar and was a slow-climbing aircraft even at the best of times.
The final variant was to have crew and fuel-tank protection, but was still under development at the end of the war. The D4Y5 Suisei Carrier Bomber Model 54 was to have been powered by a Nakajima Homare 11 of 1,825 horsepower, and was scheduled for production in late 1945. As this was never built, total production of all Suisei variants came to 2,038.
The Suiseis last sortie was made on August 15, 1945, when Admiral Matome Ugaki led eleven planes in a final inconclusive attack on Okinawa. Lacking crew armor and self-sealing fuel tanks as it did throughout its career, the D4Ys splendid speed and range were, in the final sense, wasted. Armed hardly better than the D3A, and being escorted (when they were available) by Zero fighters only slightly improved over the same models used in the Pearl Harbor attack, the Suisei must ultimately be counted as less successful than its predecessor. It has faded from the memory of all but the most knowledgeable air enthusiasts.

Excellent read . . . just heart pounding.
Gehres kept in mind the lessons learned at the Battle of Midway. He remembered that when the U.S.S. Yorktown, CV 5, was sunk, our destroyers had delivered the final torpedoes that destroyed her. He had heard the rumor that men were trapped below decks on the Yorktown when she went down.
Were "the rumors" ever proven one way or the other?
