Yes. Its a shame it had a crash. Without the 707 there would be no Boeing aircraft. No 747s, 787s, nothing. And Airbus would probably have taken over the commercial aircraft sales business. Did you know that during the 707's prototype, the Dash 80, the pilot was told to impress people. So, he started to do a barrel roll! Thankfully the Dash 80 wasn't put in too much danger but I bet it gave the Boeing guys on the ground a real scare!  ;D Here a video of it on YouTube: http://www.youtube.com/watch?v=3IV9PZW1N9U
