The first test flight of the space shuttle was a glide test performed after being released from the back of a Boeing 747 Jumbo Jet.
For those commenting on the music that you can hear I can assure you it was not added by me. It was already part of the clip when I came across it. I understand those that prefer to hear the official air to ground track (I am one of those too) but still thought that this clip deserves to be seen by as many people as possible.
