Is the deck crew going to have some sort of damage model?

[G*Man]

It absolutely destroys the immersion if it is possible to drive over crew members without consequences.
Of course, no blood should be shown here. 
However, it's like an airplane collision (with friendly plan): It leads at least to friendly fire, in my opinion even to mission abort.

[Nealius]

It breaks immersion with them standing in the damn landing area after I've already called the ball. It breaks immersion with them failing to move out of the way of an impending collision like an actual human would.
