I hate to sound like a choosy beggar, but any chance of putting it on a less-skeevy download site? How about a Dropbox link?

Sure thing: https://www.dropbox.com/s/i5eucyo7gm67bv6/SR-71%20Blackbird%... I don't really use dropbox any more so bayfiles was just the first thing that came to my mind, it's better than most free file hosting sites (no waiting and no excessive throttling)

Awesome, thanks! That worked.

I flew an L-39 with inoperative ejection rockets. The bailout procedure was: 1. Roll inverted. 2. Trim full nose down. (Down = skyward at this point.) 3. Blow canopy. 4. Fall out.

So... What do you suppose the chance is you would have hit the tail fin?

I liked "Maximum altitude is 85,000 feet. Do not fly over 85,000 feet unless you have prior authorization" "No turns are allowed over 70,000 feet. Descend 2,000 feet prior to making any turns is recommended"

"The ANS is an inertial navigation system employing a star tracker to eliminate gyro drift and to limit position error."

Not your run-of-the-mill airplane, that's for sure...

"Intentional spins are prohibited. The following technique is suggested if an inadvertent spin occurs; however, ejection may be the best course of action because spin recovery has not been demonstrated and is considered extremely unlikely."

Reminds me of my favorite line in the US Antarctic Program Field manual:

18.1i Crossing Crevasses ... If a snowmobile or sled starts to break through a snowbridge, experience and circumstances will dictate whether to brake and attempt to hold the fall, or continue driving forward in hopes of getting across before a catastrophic collapse of the snowbridge. In either case, a change of underwear is recommended.

Must be nice to have that luxury. The same emergency in the AH-1Z basically says "good luck." Granted, a hydraulic failure of two redundant and independent systems is astronomically unlikely (and the outcome will almost certainly be fatal).

Triple system failure https://en.m.wikipedia.org/wiki/United_Airlines_Flight_232

“The crew contacted United maintenance personnel via radio, but were told that, as a total loss of hydraulics on the DC-10 was considered "virtually impossible", there were no established procedures for such an event.”

Imagine letting the nose fully roll over and having to time the ejection at max inertia... or you are doing a Dr. Strangeglove meets True Lies. So delightful.

What about seatbelts?

So, I think the intent is to roll inverted, and pull up, pointing the nose at the ground. The forward momentum means that when you fall out, you'll separate from the plane as it shoots ahead of you, and you'll be sent down and behind.
