That's so interesting robomatic! I remember when Boeing jets first began to appear at London Airport (I could see the control tower from my classroom window, and watch all the take-offs and landings when I should have been paying attention to the teacher!) The jets were much louder than the propeller planes we were used to.
My first ever flight was in the sixties, in a Boeing 707, London Airport to Montreal, with BOAC. (The airport wasn't called 'Heathrow' in those days) That was sixty years ago.
As a small child my father often took me to watch the planes (anyone could get into the airport in those days - no terrorism and hardly any security!) Queen's Buildings had a viewing gallery on the roof, and there was a little toy train called the Peter Pan Railway for children to ride on.
We lived quite near London Airport, and my father helped me to identify every plane that flew over our house. He'd been in the RAF during the War (so had my mother) and we were all flying mad!
