I think people were a little less sensitive in days of yor - maybe WWII with its losses were fresh in the mind. Remember at Farnboro' in 50s when John Derry was killed Neville Duke immediately took the Hunter up - and the show went on despite crowd casualties. - similarly it went on when the Atlantique crashed in '68. Stiff upper lip. Neither would happen today - just look at Shoreham. No judgement- just fact.
