I'm with Stallie,
The flight dep at 11.45PM Local Time - according to Monday's 'West' and was due to land at dest at around 1AM.
The flight load could just as easily have been 'split' - obviously night flying was not an issue - and the aircraft done two, or even more if req'd, trips.
It was only a little over an hour's flight time...
Even back in the 'old days', with the client I was flying for, the business manager and the project manager never flew on the same aircraft - well not in my experience anyway.
Sad event.
