Jknight, in fact you DO need jet time for this observation. If you had more experience, you would know that the elevator did not run out of authority, as that would have brought the nose down with a great deal of force. The pilots are a little more professional than that. The tail is swept, just like the wings and unlike the 172 you are learning in, and when a swept wing quits flying, it breaks over, unlike a straight wing that just kind of bottoms out/flutters and starts to descend. We don't do full stalls in jets like we do in 172s. Why? It's dangerous and you'll lose a lot of altitude. You do stalls at 3000, jets must be a 10,000 to even practice stall recognition and recovery. I know you are use to lowering the nose when you get the 1st indication of a stall, but in jets we leave the nose where it is and power out of it. Unload the wings on a jet, and hang on! Didn't know I was going to be giving instruction today.
Thread hijack alert!!!!!!!, or maybe just a slight change of direction.
You do NOT power out of a stall on a swept wing jet, when you practice "stalls" in your sim, or your airplane, you are practicing recovery from an
approach to stall . I don't know the numbers for your airplane, but most transport catagory aircraft will give a stall indication at around stall plus 7%. It is that seven percent that allows you to use power for your recovery. If you reach true aerodynamic stall in a swept wing jet, you WILL NOT recover with power alone. I speak from personal experience.
The latest in upset recovery training makes this very point. You don't recover until you push over and break the stall. In fact, the proper recovery could actually be to pull power off if you stall in a nose high attitude while flying a jet with it's engines slung under the wings, because the thrust vector rotates the nose up in those airplanes.
The swept wing may be different from a 172, but it still follows the same basic law. Too much angle of attack, and it stalls, and stays stalled until the angle is decreased.
If you go back and re-read your own words, you'll realize what I mean.
sorry for the lack of development in this post, it's been a long day.

PS, it's been a while since I flew a Lear with its marginally swept wing, but that airplane is restricted to being flown by factory test pilots when it is test flown after wing work that requires any type of flight near the stall regime. Specifically, if the leading edges were removed, the factory sends a test pilot to make the first test flight because the stall characteristics are considered too much for an untrained test pilot.
