Though the T-2 has been replaced as a trainer, a few are still in service as chase aircraft. VX-20 has three.
I got to fly T-2s going through TPS. Nice airplane – once you got into the thing. Clambering into the rear cockpit was quite a climb. You had to be a decent alpinist to do it. Once you strapped in, though, the cockpit was roomy, a far cry from the wretchedly cramped TA-4. You almost felt like you could bring a cooler along for the flight. It handled nicely, too. And was, when I went through, one of the few aircraft in the TPS stable that was cleared for spins.
Which meant that it was the spin demo platform. Erect spins, of course. Then inverted spins. And TPS had an inertia coupling demonstration…you put the airplane inverted, started an inverted spin – and applied full aileron. The airplane flips in all three axes. You’d throw up, if you could figure out which way up was. Disorienting from the back seat, and good for about -4 G in the front. I wish I had a video of it. I know one exists, but don’t think it ever made its way to YouTube.
