I would assume not. I’m not sure I’d ask a retired DC/MD/now Boeing test pilot about that because I’m afraid the answer might be “oh yeah, you should try it in an MD-11”

Like, four or five times in the last year there was a really idiotic derail in that thread and I was half way through typing out "loving move on and talk about bumps on F16s or something" and then I checked the title and went "whoops, not mod here." edit: once in a while the reverse happens. Something dumb is going on here and I'm like "ugh, maybe I should drop a comment in the mod forum or PM whoever runs this sub to give them a heads up that poo poo is getting stupid. . . . wait a minute."

I posit that DC-9s are always thread relevant. The only thing that could make it more cold war is if it was delivering a nuke.

This is the only info I've seen on that test: https://www.avgeekery.com/time-boeing-717-went-inverted-testing/ The wing roots of an airplane are supposed to stall first so you still have roll control throughout a stall. In the video presumably the entire right wing stalled causing the plane to roll on its back and depart from flight control.

Some rando on Reddit says:quote:In this case the two wings were not aligned equally which created a stall in one wing prior to the other which induced the roll. That plane was the only flying one that had that condition. Hell of a recovery especially when they were anticipating the nose would drop straight down. quote:I hear you but we ended up having to put in place additional checks when we mated the wings together at our subtler in Palmdale. It was a tooling issue that created the situation to begin with. Another one of those times when all the holes in the various processes lined up perfectly to create a fault.

Then based on the age of the video they might've even deep stalled C-9s for the navy!

I'm curious if anyone could tell what their altitudes were when they lost control and again when they regained it. It looks to be... a lot less.

Captain von Trapp posted:I'm curious if anyone could tell what their altitudes were when they lost control and again when they regained it. It looks to be... a lot less. 15000 down to about 9500ish. The co-pilot taps the pilot on the arm as they're passing 10000 and they level out soon after, still it's like 5000 feet in 30 seconds.

I will forever love the Indian space program for solving an engineering test problem by sticking a communications satellite on a wooden ox drawn cart They needed to move it around for the tests and they couldn't use a truck as the metal interfered with the communication array, so instead of building some wildly expensive test site or vehicle or whatever they stuck it on a wooden cart, and towed it around the test range.

The second the stream hit the ground, Mythbusters tested peeing on the third rail, and found that the stream is so broken up by the time it hits the ground, it doesn't carry electricity well. Then again, that was with a few hundred volts, and a 100kv+ line will probably behave slightly differently.
