Mike,
Before I really flash I'd like to know if the objection to a straight and level (visually judged 300ft MSD as you say) entry to display is that it is somehow stunningly dangerous and will inevitably cause wanton death and destruction as it will be over a built up area?
And also, as the man with all of the facts, are in a better position to make the call that it is so stunningly dangerous than the operating authorities, and hence are trying to get it turned off, because of all of the wanton death and destruction that will happen when 9 aircraft fly at 300ft together in formation.
