I have no idea peter, just got the link off the Willys Tech mailing
list of all places.

She was in a pretty tight turn just before the dive, accelerated stall
maybe??

Anyhow, it was a beautiful machine, gotta make you cry doesn't it?

It was the dreaded downwind turn. Too low, too slow. Google foe vids.

Since R/C flyers depend on visual cues, they do suffer from the downwind
turn syndrome, where the model's groundspeed looks OK, but the airspeed when
flying (or turning) downwind, isn't adequate. I've seen more than a few
crunched R/C aircraft because of this. Remember, it is a visual cue thing,
not an aerodynamic issue...

Yes sir, I have many years and hours of experience flying RC's, I was an RC
instructor for our club also. If you look at the video it had already made the
downwind turn and flew quite a while before the crash.

For RC's, it is a real thing, only because of the skewed perspectives
involved. IMHO In other words, it looks like the model is going fast enough
to avoid stall, but a good portion of that perceived speed is because of the
downwind drift. Turn too sharp, low airspeed, high speed stall, = smoking
hole.

Didn't stop full-size airshows, and there've been significantly more
than a few people killed at those, as recently as the 80s and 90s.

What's so bad about people building giant models if they take
satisfaction from doing so? I certainly got a kick out of seeing it-
an amazing demonstration of design and fabrication skill.

I prefer flying full-size A/C too, but I don't go around dinging the
R/Cers and flight sim junkies who spend more than I do on my real
plane to build 737 cockpits in their garage (c.f.
http://www.737sim.com/).

Cheers,

I just think of the "Giants" as homebuilt UAVs.

My impression was that it 'stopped flying' before it looked like it stopped
flying. I think that's what dooms many a pilot because they continue to
pull after the aircraft as already stalled but before any sort of break.

Looked like the dreaded downwind turn to this old RCer

And yes, there is no such thing as a downwind turn except as an optical
illusion that effects the pilot.

No spectators have ever been killed at an airshow in the US.

It looked to me like it had already made the downwind turn and was turning
back into the wind when it crashed.

What about loss of radio contact (perhaps a transmitter or receiver
failure)? I've seen that happen. It looked like perhaps it was entering
a turn at the time, but carried on rolling until the nose fell through
as if some spoileron/aileron input had been added but never taken out.

I went back and looked again. It did look like a stall out of turn to me.
It appeared to be perfectly oriented for the 'downwind' turn type of event.
I've seen many dozens of them (done a few myself). The clouds and the sock
suggest that et was a blustery, variable wind day which just makes it even
more challenging to fly. There appears to be a momentary bump where the
nose drops and the bank increases well before the turn completes 90
degrees - that looks like a stall. Did this thing have true to scale
spoilers for bank?

Having said that, there's no way to know for sure without telemetry. Flight
instruments is part of what makes full scale flight easier in so many ways.

Damn what a fine looking ship!

Agreed. People do super large for the same reason they do immaculate
finishes, mind bending scale detail, and flying lawn mowers -
owner/builder's ego.

I was thinking how sad it was to see it crash. Then I remembered how sad it
is to see some great flying model moldering in someone's garage because they
moved on to newer projects.

The great thing about models is that crashing is a (relatively harmless)
part of the game. I'm looking at the crew working with the B52 and thinking
of the great stories they have about the model "you just can't imagine how
well if flew..." and "you should have seen the fire....."

Anyone want to talk about the morality of modeling weapons of mass
destruction? Nevermind.

Don't mean to sound like I'm picking nits because I fully understand
that you're talking about flying aircraft. We did, however, have a
death at an airshow at Willow Grove NAS about twenty years ago. They
failed to disable the ejection mechanism in a fighter and a young boy
ejected himself and got killed. That was the end of the airshow for a
number of years. Very sad situation.

Didn't realize that- just figured there hadn't been any spectacular
disasters as have been seen in Europe.

Just one more piece of evidence that as much as well enjoy dinging the
FAA, it's clearly the best agency of its kind in the world, dealing
with by far the largest and most complicated set of needs.

Of course, US pilots & airshow organizers deserve credit as well.

Best,

Aircraft are never flown over or toward spectators in the US with one
exception. That is the Navy and Air Force demo teams. Not sure how
they get away with it but they clearly fly directly over the spectators.

It looked to me like the pilot might have gotten confused which wing
was low and then corrected the wrong way. As the roll was continued,
the nose fell through. When an RC plane is flying and the light is
behind it, its often easy to get confused which wing has dipped to
know which way to correct. In that circumstance, you only know you've
got it wrong when it responds the opposite of what you thought it
should. A normal turn would have been back towards the camera to come
back over the runway, not away as he ended up doing and crashing.

I understand the illusion of the "downwind turn" to an RC pilot and the
difficulty to keeping it straight in your mind which way to apply aileron
with the model coming at you.

However, there was a famous video involving a real B-52 at Fairchild AFB, WA
where the pilot was hot-rodding low passes and turns. The old bomber
overbanked and spiraled in just like the model did in the video - except the
real B52 only managed 1/2 turn before impact right in front of the camera.
I'm wondering if this is a real behavior of the B52 that was accurately
modeled in the RC crash. If so, it's a credit to the accuracy of the model
builders. Sad to see their loss.

That plane had redundant systems to avoid that sort of problem. I agree about the 'downwind' turn. Did you hear the wind
blowing in the microphone? The weather did not look good...

It's a little hard to imagine that a pilot susceptible to that particular
challenge of RC flying would be flying the B52. I flew for many years and
yet never completely got past my training that included pushing the stick
towards the down wing when it's coming at you. My brother is an
accomplished pattern flyer and I recently asked him whether he still used
that. He laughed and tried to explaing that he 'is completely in the plane
and always oriented". Anyway, it was a pretty simple turn, a large
aircraft, and close in... I don't think so.... but without a black box,
we're all guessing.

In any case, I've watched so many RC aircraft bite the dust in this way.
Usually on the turn from downwind to final. It was SOP to blame the radio,
and back in the 60 and early 70s, that was more than plausible. But I
remain convinced that the vast majority of those accidents were stall-spin.
Back then, all modelers had free flight and other experience. Practically
all RC planes were test glided before first flight (long after it was
practical for the higher loaded ones). A stall was known to require a nose
up deck angle and would typically have a clear break after a noticeable
deceleration.

On the otherhand, accelerated stalls and turning stalls occured all the time
and yet they were infrequently identified as such. The B52 crash is what
such a stall looks like. If you look closely, you can even see the break.
If he had been higher, a spin or at least a steep spiral would have
developed. But it is all just conjecture.

I watched a full scale glider do a such stall on the turn to final. The
reasons for getting too slow were unclear but the pilot immediately knew it
was a stall going into a spin. He saved his life by correctly applying
corrective down elevator and perhaps rudder. After recovering into a pretty
steep dive he leveled the wings and pulled out just in time to pancake onto
an interstate. Blew the gear and crunched the belly but didn't even ding a
wing tip. We got him out of there before the State Police even showed up.

That does not sound like a mistake that a modeler capable of making such a
beast would do.

If you mean the crash at Fairchild, that was a B-52.
There hasn't been a B-2 crash yet. At least that we know

Oh yes it is...It can happen to any R/C pilot.

I've seen some outstanding R/C fliers have "Oh Sh*t" moments at the worst
possible time...usually resulting in a pile of kindling (or busted up
fiberglass, in the case of one particular, 8' long Byron Originals F15
Eagle...)

I have a neighbor (who is a very accomplished fixed-wing and helo R/C
flier...) who has been working on a 1/5 scale B17G for the past 6+ years.
He just took it for it's maiden flight this past weekend and, you guessed
it, ALL GONE in one rib cracking instant !! I don't have all the horrible
details yet but his wife says he's one seriously bummed puppy.

It was an amazing model:

- Four four-cycle engines (#3 could smoke on demand...) which sounded so
sweet
- Scale Retracts
- Pneumatic Brakes
- Bomb Bay that openend
- Landing lights in each wing (came on when the gear was down)
- Fabulous paint job

But like they say: "If you aren't crashing...you aren't flying."

Ahem...This applies to the R/C world only!!!

I always thought I was a rather poor RC'r, but I guess I must be pretty damn
good, because I don't even make that mistake.

Given. There are a million other ways to screw up, with the stall spin, or
downwind turn being just a few of them.

I read it off the web site, very interesting but took me about 1/2 hour.
Just goes to show what happens when people stick their heads in the sand
especially the middle management that were afraid to pass on "bad" news to
their superiors!

Sort of. The B-52 crash at Fairchild was a simple accelerated stall, no
spin. It stalled at a near-90 degree bank angle and slid sideways into the
ground. Very tragic. There was a white paper written by a USAF major some
time afterward that examined the leadership and airmanship climate prior to
the crash that makes fascinating reading. I may even have an electronic
copy of it if anyone's interested.

The issue I was trying to point out wasn't the control "reversal" new
R/C pilots experience when the model is flying towards them, it was
related to the limited (albiet fantastic) dynamic range of the human
eye. When the model is back lit you just see the black siloette. In
this circumstance, the image the viewer sees is ambiguous as to which
way the roll has begun and thus the pilot doesn't know which way to
correct. You can see this in the video because the camera is even
more limited than the human eye.

A terrible tragedy.
