You see a bit of both, specially DERP Pilots just can't take off, so instead of press R, they do just move forwards until lift, many times crashing on the landing pad. I'm myself the crashy pilot.
Like visually it is what you see, when you get to play it, you notice the changes to the Flight Model, so i guess they're focusing on that before they focus on all the transitions and collisions. I really can't explain well what's off with it currently, something is!
I hope somebody else around can go more technical on it, there's people that go much more in depth with the flight model and can review the changes to someone who played older versions to the current one.
I know it's not a major jump like a new flight model, it's the old one, improved, specially when it comes to controller balance. If they keep the work on this they will get this weird movement and collisions right.
