I believe this one. The lear has a fast rate of roll. None of the YouTube videos show someone trying a high rate lear roll.
The owner of one company I worked for rolled right after take off at about two hundred and fifty feet. By the time I realized what he was doing we were already upside down.
Another company I worked for used the Lear on a military contract for radar training and some air combat maneuvering. If the tiptanks are empty the airplane can be maneuvered very aggressively in roll without damaging the airframe.
I did two re-certification flights in two different Lears over the years with Lear Test Pilots. One was after a bird strike and the other required some access panels near the leading edges to be removed for wing tank work.
Those guys throw the Lear around like you wouldn't believe. Nothing stupid, they didn't roll it, but 90* of bank was reached several times as well as probably 40-50* of pitch up and down. Not too mention about 20 stalls on each flight for the certification.
You know how in the Lears you're supposed to bank to 90* to let the nose fall through the horizon to recover from a nose high-decreasing airspeed unusal attitude....because they do not like negative G's.....it feels, looks and works exactly like in the sim.
