Other than flying to low, what happend to this B52? Looks like his angle got a bit past vertical which drove the nose down.

That happened years ago. A hot dog pilot made a turn at too low speed and fell out of the air. The real tragedy was the loss of the crew.

Here ya go:
http://en.wikipedia.org/wiki/1994_Fairchild_Air_Force_Base_B-52_crash

In short (and think’n big):
Big airplanes don’t do anything very quickly.
Big airplanes, when slowed down, do make big fireballs though.

Big egos and big airplanes don’t mix.
One big ego will often kill three little egos.

DJ adds (from across the office):
"Girls make better big airplane pilots then boys."

DJ is absolutely right.



seriously – the sad part is the loss of the crew at the hands of a hotshot pilot.

An airplane has a "stall" speed at which the air flow over the wings is disrupted and they cease to generate lift. The speed varies based on the design of the aircraft of course. A Cessna 172 may be 43 MPH and that B-52 may be something like 150 MPH (just a guess). This rated speed is while the plane is flying straight. Changes in attitude like turning effectively raise the stall speed and if the stall speed intersects the current air speed, the plane quits flying.

You can see in the video, the right aileron is at full deflection - the pilot is trying to level it out but because of the air flow disruption, there's no control authority even though the plane is still moving forward through the air.

During flight instruction, I was reminded on many occasions while doing pattern work not to get too eager and try to turn too soon after taking off for this very reason.

That Wiki article explains a lot of this in more detail.

^^^^ I hate that alarm. Heard it a few times. In tight turns. Pucker factor = 100%. Cessna 182 amphib.

As told to me by a crop-duster during my college summers:

There are old pilots and there are bold pilots, but there are no bold old pilots.

WVO is dead-on. I remember that crash... it was in prep for an airshow, IIRC. Senior pilot, hot dogging for his buddies, trying to fly a heavy like it was a fighter... sad.

I have been learning a little about flying lately (vicariously) and am amazed at all there is to know about it. I have a new-found appreciation for pilots and a lot of respect for those who do it well.

On accelerated stalls....

In the 1970s, when I was in the CAP, we had an SAR mission looking for a missing/presumed lost Piper Lance (it later turned up intact in California) and we kept getting intermittent ELT signals when flying in one corner of our grid, near Lake Travis.

Ground crews drove to the various small airports in that area and checked all the aircraft for triggered ELTs but couldn't find anything. We found out later on that the day before, a guy in a 150, buzzing his buddies who were out on the lake had managed to get it in an accelerated stall and spin into the lake. Miraculously, he survived but, the aircraft was in about 90ft of water with the ELT still transmitting!

It's worse when you have to go into a stall.....

Just as sad, is to read all the stunts (crap) he pulled before that flight, and nobody said anything to him or did anything about it.
That alone has to be driving the families of the other crew members crazy mad.

Just wait until you don’t have to go into one. But the “aviation gods” hand you one anyway.

Showing off for his family and friends on the ground IIRC. The BUFF is not a stuntplane, and his lack of good judgement cost the lives of six service members and a relatively rare almost antique aircraft. He went into a stall waaay to low and there was no way he could get enough airspeed at that altitude to recover.

Very sad mishap indeed. I would wager there wasnt enogh left of the crew to fill an aspirin bottle after that fire.

You're not supposed to like it.

But seriously -
A lot of that can be caused by simply “mushing the airflow” over the stall sensor while performing an elevator turn at most any safe airspeed. If it stops the second you release elevator pull, you’re fine. No pucker factor.
If you release the elevator pull and you still hear it: Pucker factor should be about 15 on a 1 to 10 scale.

Another thing to feel good about: The drag of, and CG change caused by, the floats can help pull the nose to an airspeed gathering attitude (down) more expeditiously than without. Yes, they cause more drag. Which normally hinders speed. But they can be thrusts friend too, when teamed with gravity. That is – If you have the altitude.
