I'd like to know what spectacular take-offs everyone has seen. I've seen a few that made lasting impressions..
The first one that comes to memory was when I watched an Air France Concorde take off from Brown Field in San Diego back in 1989. I was at the end of the runway, waiting. I heard the roar of turbojets, then saw a cloud of black smoke. Then I was a white object hurtling down the runway, picking up speed. I watched the nose rise, then the Concorde lifted off at a high angle, banked slightly, and ROARED overhead. I took photographs the entire time. The sound was deafening, but what a thrill!
Another take-off I saw - I was at Pulkovo Airport in St. Petersburg, Russia. It was very foggy, and the end of the runway is far from the terminal. I heard the roar of jet engines, and looked towards the sound. One of Aeroflot's huge IL86 airliners had just lifted off and was climbing into a clearing in the fog, engines at full throttle, landing gear still cycling up, and it seemed amazing to me that something so huge should become airborne. It lumbered across my field of vision and into another fog bank and was no longer visible. What a rush!
The most recent take-off that just brought tears to my eyes was one I saw at Chicago O'Hare a couple weeks ago. I was going back to my car in the short-term parking lot after having seen the mother of a friend off on a flight back to Russia. I heard the familiar sound of engines at full throttle, looked up and there was a HUGE Lufthansa 747-200, having just rotated and gear cycling up. It was so close, I could almost see passengers in the windows, and the roar of its GE engines was thunderous! The 747 is quite majestic on take-off as well. I watched it until it was well out of my sight, then went to my car and drove home.
