If it wasn't so heavy, it would.
The issue here is that on server restart or logging back into the game, the ship you are in spawns back with 0 momentum, so the wings etc are not generating lift, so it just plummets to the ground.
Same sort of thing happened to me yesterday, travelling 30,000km/h in space, server restart, spawned back in at 0km/h, not enough space fuel to get back to 30,000 km/h and have enough to reverse burn to slow down.
