Has it actually been shown, anywhere, that they were in fact "late" ?? The only reference I can find to them being "late" is the television comment by Mr Moore .. just why is his word given so much credence ??
Most flypasts EITHER have a specific time or the aircraft are "called in" by ground comms .... which was the case here ???
If it was a SPECIFIC time ... just how far "off" were they, if any ??? If they were "called in" then it probably wasn't their "fault"... either way .. there are an awful lot of assumptions being made in this thread .. and very few facts .....
As I was always taught ... don't make ann ASS out of U and ME
