Sending 4 jets to an air show can be easily justified. What is criminal is sending 100 maintainers to look after 4 aircraft ! An outrageous waste of money. I'd love to see the business case for that one.
.......... and a pre planned exercise! You have no idea what it takes to maintain jets a long way from home, 100 sounds about right. Seadrills, one could argue a navy warship only has one steering wheel so why all the other 'hangers on'
