Default 707 does a roll -- video

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


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! :-)
