For me the SR/71 but my father reckons 9 Lightnings at Farnboro in the 60’s was unbeatable as the compression stopped him from breathing.
I was there also. It was pretty damned impressive. I think my hearing went on a downward curve from that day! It was the most incredible sight to see them take off in a stream and seemingly climb ‘near vertical’ – one after the other.
I wonder if there is any film out there of the event?
