"Gee our old LaSalle ran great!"
I remember it well--often used the drug store's tube tester. One of the big surprises for me about recent technology is how reliable solid state circuitry has become compared to tubes--several orders of magnitude more so.
Yep, the advances in technology really are amazing. But I still can't fly to work like George Jetson.
But you can have Dick Tracy’s two-way wrist radio.
I was promised a flying car. I want my flying car.
Thanks. And thanks for your additions to the threads over the years.
I saw a slightly more sophisticated version at Buchenwald, but there wasn’t an illustration on how it worked, and if there was a written explanation in German, it was beyond my skills. (It wasn’t long after the opening of the border, and there wasn’t much material there in English).

Black Panther Historic Shipwreck Preserve
On April 20, 1944, U-1105, a modified Type VII-C German submarine, built at the Nordseewerke Shipyard at Emden, Germany, was launched to begin its brief and dramatic wartime career.
Formally commissioned into the Kriegsmarine on June 3, 1944, U-1105 was one of fewer than ten submarines produced during the war outfitted with an experimental synthetic skin designed to counter Allied sonar devices. The submarine’s commander was a 25-year-old lieutenant named Hans-Joachim Schwarz.
In the spring of 1945, U-1105, nicknamed Black Panther for the black rubber coating, was deemed ready for its first and only patrol.
In March of 1945 the submarine sailed from Wilhelmshaven for Kiel. It took on provisions, fuel, and ammunition and torpedoes, and in early April sailed from Kiel to Norway to conduct final testing and crew training before setting out on patrol. From the south coast of Norway, U-1105 set a course for the west coast of Ireland, eluding Allied air patrols, sub chasers equipped with ASDIC, and at least one large English minefield along the way.
U-1105’s mission was to patrol along the Allied convoy routes in the vicinity of Black Rock, Ireland. On the morning of April 27, 1945, the sub detected a patrol of three British destroyers. At a range of 2000 meters the submarine fired two acoustic torpedoes then dove to 100 meters to escape a counterattack. The accuracy of the two torpedoes struck the HMS Redmill, a 1300 ton TE Captain Class frigate, disabling the stern and killing 32 men. The U-1105 managed to sink to a remarkable 570 feet and remained undetected by the Allied search that ensued.

Seven days later, Schwarz received word that the war was over. The U-1105 was ordered to an Allied base in northern Scotland where it surrendered. The British later turned the submarine over to the United States Navy for study and experimentation in the U.S.
After preliminary testing the U-1105 was fatally damaged on September 19, 1949 and was sunk in 90 feet of water in the Potomac River at Piney Point by a Navy Explosive Ordnance Disposal team.
