Assume you are talking about the Fairford shuttle fir RIATs. I was in Day Pax at Lyneham taking the bookings those flights and liasing with the Ops Cpl who was arranging the flight.
As we understood it from Ops the landing time at Fairford was the critical thing - miss it and the flight wouldn't happen.
So we had planned on a 1 hour report. Yes 1 hour - so that when everyone turned up at the hour the pax desk would have a chance of checking you all off against the planned list and having a fighting chance of finishing off the trim, (Even 7 minute flights need a trim sheet) putting you all into the outbound lounge (safety video - does teh ALM not do saftery breifs on 7 minute flights?) and getting everyone out to the aircraft.
Why use the outbound lounge? Surprisingly enough you werent the only flights going off that day and it was the easiest way to ensure the right people got onto the aircraft.
So why did it change to a 2 hour check in....OC Police got to hear of the flight (not exactly a big secret as it was in orders). 'They are passengers so they need to be security checked'. He wouldn't comprise, everyone had to be checked or they couldnt fly - report time had to be increased to 2 hours to allow for this.
