I wasn't there at the time so I can't comment on this alleged incident.
Rule 70 says
(2) (a) The commander of an aircraft intending to participate in a flying display shall take
all reasonable steps to satisfy himself before he participates that:
(i) the flying display director has been granted an appropriate permission
under paragraph (4);
‘Flying display’ means any flying activity deliberately performed for the purpose of
providing an exhibition or entertainment at an advertised event open to the public;
One assumes that the comments above come from those who have read
CAP 393 and are happy that the rules were complied with.
If the PFA were resonsible for safety at the event it might not be unreasonable for them to object if they thought the rules were broken. Perhaps it would be best to await the result of the investigation. If no rules were broken, there should be no problem.
