"the RAF are always keen to have infringements investigated in ‘a most thorough way’."
Are they just as keen when it is they that infinge or step outside the legal limits? It was very very stupid of the pilots to go anywhere near a TRA and cannot be condoned at all.
"Red 1 spotted all of them as he led the formation past and called a halt to the display, which he seemed to agree with as the safest option open to the Arrows (I agree!). "
As for Red 1 seeing the a/c in the TRA why was he not informed earlier by the appropriate radar unit? Surely the Reds were in receipt of some kind of service from the nearest military radar or were they assuming that the TRA would protect them from idiots (oh and birds)?
