707 does a roll -- video

What I meant was, during the interview, I though I heard Tex call it a
chandelle.

It was a true barrel roll. He had to keep pressure in the scavenger pumps
and this required positive g all the way around. The g was above 1 going
in and back to level flight and at 1 through the roll. (through the roll
BTW is where I describe barrel rolls)

I'm sorry, but I've not seen this interview and he never mentioned Chandelle
with us that I can remember.
Just off the top of my head, he might have been referring to the extreme
high nose attitude he had to attain before initiating the roll off the
climb. The roll he did had an extremely loose and wide parameter and in
order to keep the exit speed in line he couldn't allow the nose to get WAY
down in the recovery. This required a VERY high entry nose attitude above
the horizon so that when past inverted going around, the nose attitude on
recovery would be low but not THAT low. After recovery, he just eased the
bird back to level flight from it's nose low position.
The reference to a Chandelle could have been Tex's way of emphasizing how
high the nose actually had to be, and not so much a direct reference to a
Chandelle being performed.
Personally, I'm not qualified in anything that large, but my guess based
simply on the energy involved would be that the Dash 80 would be VERY hard
pressed to perform a Chandelle without stalling out due to drag rise before
a max altitude/180 degree position change had been reached. Could
be.......but I'd like to actually see that before I'd believe it. However,
if anyone could do it, Tex would have been the guy to try it! :-)

Great guy, and he pulled off one hell of a stunt back there with the
prototype Dash 80! We always kidded him about it looking like a "whale"
roll!!! :-))

Hey Dudley,

Speaking of whales... D'ya think the structure (spars?) on the A380
would hold up to a barrel roll? Airbus could use some positive press
for that program right about now. That'd be even more spectacular than
the photos of the A380 four-ship from last year!

I hope it could hold up to 1 g. According to the history channel, the
head guys called the pilot to the mat and brought in some engineers.
Their main concern was that the aircraft was not certified for neg g's
and they thought fuel/oil/etc could unport. When the pilot explained to
him that he never got over 1.5 g's they seemed calmer.

I listened to a talk that Tex gave in the cafeteria of the 40-87
building in Everett back when I was working there. It was probably
1992 or 1993.

His talk was about a P-39 aircobra that he was involved in modifying
for an air race. One of the things he brought up early in his talk was
about how the landing gear came up in less than 2 seconds.
Unfortunately his memory was getting pretty bad and he kept asking if
he had brought up the fact that the landing gear came up in 2 seconds
throughout his talk.

Yes, I know that old age memory loss is not a laughing matter...

He came and talked to our EAA Chapter about that time, and we discussed writing
after he signed a copy of his book for me. About nine months later, we happened
to meet in an elevator. He remembered me, and that I was a fellow author.

Wasn't all gone....

The nose goes down and has to be pulle dback up, no?

No. Not crashing afterwards was not part of the requirements.

Ok, (responding to myself), I was responding to the wrong scenario. For
Tex Johnson's 707, not crashing was important. I was thinking of the
theoretical question in a different (sub?)thread.

Had a Q&A once as a guest speaker on aviation with a troop of Cub

When you flew during the war, was it the blue or the grey?

PLEASE Matt!!! Try to be "CIVIL" here :-)))))

"...three if by air"

I wonder if the other side's pilots wore red coats. :-)

Not just for Jose, but for everyone in this thread, Tex spelled his
name "Johnston", and he did not roll a "707".

From Wikipedia:

Alvin M. "Tex" Johnston (August 18, 1914 - November 14, 1998) was a test
pilot for Bell Aircraft and the Boeing Company. He is best known for
rolling the Boeing model 367-80 (better known as the Dash-80, the prototype
of the KC-135 Stratotanker, which was the basis for the 707) in a
demonstration flight over Lake Washington on August 7, 1955. The maneuver
was caught on film and is frequently shown on the Discovery Wings cable
channel in a three-minute short as part of the Touched by History series.

Tex is gone, but the Dash 80, restored to it's original (ugly) brown
and yellow paint scheme stands in the Smithsonian's Udvar-Hazy center.
