Players can still be hurt
Ran into an issue, that myself and one of my admins were able to replicate, where players can still be hurt, due to a crushing action associated with the tail gate of the Transport Heli. 

If the tailgate area of a Transport Heli, lands on a player, or near a player (including NPC's) they will ultimately be killed. This is a huge detriment, as players can abuse this on PVE based Servers, where there should be no killing, at all.
