Don't have an answer as to WHY the red arrows pass down the runway but Punch is'nt fibbing.
Around 2yrs ago they done it while i was on shift. First was a low pass over the runway in formation, followed by a tight turn around sat1/cargo apron then lining back up for a full stop landing on rwy23. They parked up over the north side for a while aswell.
Was quite a sight.

Regards.
