Disposable...I like that LOL!! Major bucks vaporized into major (though very, very short) fun. That is truly what it is for a vintage jet...though disposable outcome would describe it better.
Truly a kick in the pants. Hack the clock, light the burner, and 3 minutes later you are 7 miles up and supersonic...
....and the student was still mentally back on the runway. A bit faster than he can keep up! In the brief I would rib them that they better pay attention, because...since I sat behind...he wouldn't be able to hear me once we passed the sound barrier. Most were gullible enough to believe it!
Truly though...it is just as exciting sitting with your rear 6 inches above the road at 70mph on the freeway at rush hour, with your arm hanging over the side of a TR3...with my head half as high as the truck wheels in the next lane. Invigorating!
