It's funny. That's it. People just find it funny.

I guess I don't really get that then - it's funny that someone designed it sensibly? Not sure where the joke is.

Yes! The standard is so senseless that something sensible is hilarious.

In a mad world, a sane man is considered mad.

I once got around two thirds through a certificate for flying ultralight planes. It sort of stopped making sense to me when we were practicing emergency landings over forest and I was told to aim for trees with thinner trunks. This is sitting inside a cramped metal can with the engine in your lap and propeller in your face. There are so many ways to die in that situation that focusing on the diameter of tree trunks w…

The same is true for gliders and has saved lives (one i know).

In a similar vein, page 3-135[0] describes what to do when e.g. under missile fire ("the pilot is authorized to use the tactical limits listed...to exit the hostile area by the most expeditious means... Subsequent reentry into situations which rely on use of these limits is NOT authorized.") on the same page as the procedure for defogging the cockpit.

Posting this here hoping that someone with more knowledge can enlighten me about this. After going down a bit of the rabbit hole, I see that the SR-71's first flight was in 1964. It has held the record for fastest air-breathing manned aircraft[0] since 1976. What is the reason that given all of the technological advances that record hasn't been broken?

Basically, satellites took over They are cheaper to operate and less vulnerable to defensive countermeasures and other failure conditions. From a Los Angeles Times article from '89 [0]:

> "The Air Force decision to retire the Blackbirds in 1990 is based on several factors. In congressional testimony, Air Force Chief of Staff Gen. Larry D. Welch identified the increased survivability of reconnaissance satellites, SR-71 vulnerability to the Soviet SAM-5 surface-to-air missile and the cost of maintaining the SR-71 fleet."

Better to think through these scenarios ahead of time so that you already have a plan if you find yourself in this situation, as others have. Tree landings can be survivable especially if you let the trees bend and absorb your energy.

I originally downvoted both your comments, but after a few seconds of reflection realized that it's not deserved, and undowned both.

I think you _truly_ are missing the point of why it's funny, and that's fine. Humour is a pretty subjective thing in the end.

Has the same kind of training. It is interesting to see the difference in culture between ultralight and general aviation flying.

In general aviation, the focus tends to be about doing things right: proper procedures, precise flying, etc... Ultralight tends to be more about getting prepared in case things go wrong. In fact, more than half of my training was about dealing with engine failures.

I think the difference in training comes from the fact that crashes are more frequent with ultralight aircraft but they are also more survivable. A big part of it is that ultralight aircraft are lighter (duh) and can fly slow, which mean mush less energy to dissipate, and it matters a lot if you are going to crash into a forest.
