This will allow to start these events when they should occur, almost for pilots who want to respect the reality. Actually with just a single "boarding" request all these actions are all wrong in term of timing.
But DO NOT disable crew boarding, like it is asked in another thread ! I mean with 3 separate requests, peoples who don't care about realism will just have to launch the 3 requests in the same time (really not a big deal). Those who consider that the game start with crew already boarded, will simply skip the crew boarding request.
who can do more can do less !
Thanks in forward to take this request in consideration
