To be fair, it seems as if the lads and lasses involved in the air-bridge have identified a number of problems and are specifically designing the "trial-bridge" around them. For example the classic line over on the green forum is "There we were, somewhere hot and sandy getting shot at, got our 2 week R&R, and lost a day of it because the RAF aircrew prats said they'd worked a long day, and the hour's delay on the ground meant they would have worked too hard". Kudos to finding a possible solution although doubtless this method will have a few snags of its own.
