I still find it mind blowing that there was only 66 years between Orville Wright's first powered flight and Neil Armstrong setting foot on the moon.
Things that I find mind blowing:
I took an eighteen year old LAC flying the other week. We were chatting away and I told him that it was forty years this year since I joined up and it seemed like ten minutes ago. I later realised that it was the equivalent of me at eighteen flying with someone who had joined up in 1934...
The aircraft we were in first flew when I was twelve...
When the Canberra retired in 2006 it had an operational service record of 55 years. Equivalent to the Sopwith Camel being operational until 1972...
Some guys who flew the Lightning are now in their 90's...
