It did occur to me the other day that SRVL has another fun aspect: How long does it take to kill the thrust on that lift system, and how long (consequently) are you gliding along the deck like a hovercraft?
I would guess that you could slam all your IGVs closed as soon as you had weight on wheels, but that might send a powerful shock through the engine. And it's going to take a few seconds for everything to stop spinning and pumping air.
