The Boeing 707 first flew.
I've flown in them many times, and always got quite a thrill out of it.
The one pictured above is owned by John Travolta, and has been lovingly restored to its full glory.
The 707 was based on the famous "Dash 80" that Tex Johnson barrel rolled, and was the prototype for the KC-135 tanker that the US Air Force still flies, although they've all been rebuilt and re-engined so many times that I wonder how much of the original airplane is left!
Truly beautiful aircraft, and they made possible the rise of low-cost transatlantic and transpacific air travel.
