JEEEEZUS....Friggin' steel cojones

Yeah, he had very little choice. That's some bit of flying, too.
Imagine, an outside barrel roll, maintainting negative G the whole
way and having to put it down at exactly the moment you ran out of
manuever and altitude simultaneously.
Mindblowing.


Steel cojones -- no choice. But someone without steel down there might
have just let go of the stick and died. (What's that psych problem,
"resignation"? Williams had nothing but antidote for that.)

The sheer presence of mind to think about a previous incident and
REALIZING that it was the same problem but inverted, and doing that in
a matter of seconds and rolling over to save your azz, and all the
other stuff -- Mindblowing.

Gives you hope if you're knocked upside down on short final by wake
turbulence -- hell it makes that seem like a relatively small
problem!!!



It is a relatively small problem if you've had any aerobatic training
and you have a bit of altitude.
Unless you cross it at a right angle and it's fresh and you're going
fast enough to do some damage.

This all asumes a light plane and something large enough to upset you
badly, say something over 25,000 lbs, though anything will give you some
lumps if you get close enough.

If you're flying parallel, more or less, to the other aircraft, what's
going to happen is you're going to roll and you're going to roll very
quickly. This roll will be smooth but extemly fast.
Unless your own airplane has a fantastic roll rate, you're going to be
on your back and nose down and probably out of the wake before you even
know what's happened.
The vortice is relatively smooth, as is the resultant roll, but it's
action is extremely strong, so the best course out of it is to allow it
to eject you this way (it's not like you get a choice here, BTW) and
then recover from the resulting upset in the most convienient fashion.
e.g, roll or split S out of it.
If you are very close to the ground when this happens, you're probably
screwed.
BTW, I'm not even remotely suggesting anyone be cavalier about these
things. They're strong and will roll you over every time and can bust
your airplane on the spot (this is unlikely, unless you're flying lawn
furniture).
I'm assuming an accidental encounter between a large wake and a smaller
aircraft. They do happen. If it happens too low for a recovery you've
ignored all the info that's out there about avoidance. In other words,
you've flown into one from a preceding aircraft taking off or landing.
