Think "boat." The weight of the boat increases it's wake. The planes weight and density increased with a full compliment of passenger, baggage and fuel. Wings are heavier with a full load of fuel.
It's all about aerodynamics and displacement. A heavier plane (like a heavier boat) displaces more air than a lighter one.
Ever driven behind a semi truck going down the highway? Ever notice that at some distances while driving behind a semi truck you get more of that "rocking your car" motion than you do at other distances?
Ever notice that while passing a truck on the right or left while going down the highway, when you get right along side it with your car's hood about even with the back wheels of the semi-tractor you get almost ZERO wind noise? Then when you go to pass in front of the truck it gets noisier and you have to correct the car because of the wind?
That's turbulence. One jet flying behind another at some distances get the same effect. There's jet wash, turbulence, and jet wake.
You can experience what jet wash, turbulence and wake feels like driving behind a truck, then going to pass. Drive real close behind the truck, and the "wake" the truck produces breaks the air for you. It's real quiet driving down the road closely following a semi. No air noise due to the truck making the wake (displacing air) for you.
If that jet got caught in the wake of a larger 747 in front of it, there might not have been enough air mass to produce enough lift to keep that plane in the air.
That's what jet wake is all about.
BTW, nice to have some sane members on the thread.
On hot summer days for example, planes have a harder time taking off because the air isn't as DENSE as it is on cooler days.
It's all about air density and lift.
From: CNN
But in the last eight seconds recorded by the Flight Data Recorder (FDR), the plane was pushed left, left and right with significant force. Data shows the rudder moved in the opposition directions, probably corrections by the pilot.
After that, the rudder stopped sending usable data, the current head of the NTSB Marion Blakey said. That is also believed to be when the pilots lost control.
The CNN story seems to indicate that the vert stab wasn't quite gone at that point, at least the rudder posistion encoder was still reporting data, and data consistent with the pilots expected reactions to yaw induced by turbulence. Things went all to snot after that though. Indeed, it does appear that the poor bastards didn't have a chance. Fortunately, it was all over quickly, for everyone on board.
So would I my friend, then I'd have to put that aside and get down to the analysis. Glad I've never had to do that, and likely never will.
The truth would also save lives by forcing the FAA to actually regulate the industry. But at this point the number of innocents killed in the air is still acceptable to EVERYONE. We are happily chugging along toward a busy retail holiday season.
Don't be a party pooper and obsess about the ugly truth. We've got to keep the ekonomy going.
Real bombs often go "krack" rather than KA-BOOM. More like a gunshot. especially if it were a strategically posistioned cutting charge. If it was way back in the tail, or on the engine, or even in the baggage compartment, you might not hear it in the cockpit, but would hear the "rattle" as the airframe shuddered. That's not to say there was a bomb, just that it might not be heard in the cockpit if there was one.
Which brings up a question. Has anyone seen a picture of, or read a description of the condition and/or whereabouts of the horizontal stabiliser?
Black is the natural color of the composite material. It is made up of carbon fibers.
The rest of the structure has been painted...
It doesn't change my position a bit, since I think most of the capital cities in the ME, not to mention Mecca and Medina, should have been nukesd in September, anyway.
LOL! Amazin', huh???Flight 587 shows a puff of smoke in the sky seconds after it crashed outside New York.
NO KIDDING!!!! REALLY - a puff of smoke AFTER it crashed. Wow, now thats news /sarcasm
Besides, if you haven't noticed, we don't have liars in the Whitehouse any more!Oh, yeah! I've noticed character quality in GWB since I voted for him for governor in our fair state!
I agree with your post completely, friend! ;-)
I guess I'm a "conspiracy nutcase goofball" because I believe in statistics. The stats move a logical mind to reasonable conclusions. Why don't you hire yourself a statistician and compute the exact odds of FOUR "unexplained" catastrophes sourced from the same airport in this time frame.
If it ends up past 1 in a billion will you be convinced?
I doubt it. You're bugged by the conspiracy nutcases? I'm bugged by the "gotta have it on video" crowd. If Woodward & Bernstein hadn't actually found the smoking gun and Nixon had slipped out of the noose I'm sure they'd be on your long list of "nutcases". In other words if they didn't get the crime on tape and you can't see it with your own 2 eyes then it didn't happen.
If the glove don't fit you must acquit.
The Coast Guard needs to look for any Luxury Yachts roaming the bay that day...sounds like a particle beam weapon.....particle beam weapon
Huh? Not being a technical wizard, you shot a little over my head there. Can you elaborate a little bit, friend???
Thanks!
