Thanks for the correction. My first flight ever was on a Boeing 707 and even in 1960’s that bird flew at 600 mph+.
I had flown on Constellations and a DC-3, I think, and remember my first jet flight with awe. Propeller aircraft at takeoff were so slow in comparison the jets, the jets seemed like an E-ticket ride at Disney. And they flew so much higher! At night, you could easily make out car headlights on the roads below, but the jets went so high, it was no way.
Yeah, I flew in a 707 when I was 10 Years Old, the first time I was ever on a Plane.
It was quite a different experience back then. On the Flight back home I was by myself and the Stewardesses treated me like I was the only Passenger. Memories...
