I'm against it because it allows for gaming the game. Too many folks taking DTs and 5% fuel, getting 3 HOs in then coasting dead stick while HOing 5 more and crashing. Rinse, repeat. There's far too much of the mindless furballer mentality now, as-is.
On the bomber side I'm against it because the bombers in this game fly too fast and climb too fast already. They should take 100% at all times, and this would only allow them to take off with 1% fuel and still have enough time to climb to 15k, drop, and glide back (probably at 2500 fpm climb rate, with that little gas onboard to weight it down).
Again, only leads to gaming the game.
