This morning I biked over to Moffett Field and the Nasa Ames Research Center to see STS Endeavour fly overhead piggy-backing on a 747. Here's a resulting photograph.
Strangely it flew over the wrong side of Moffett since everyone–even the NASA Staff–was expecting it to come in over the runway. They had announced over a PA system that it would come on a landing approach and fly as low as possibly 200ft! But it actually surprised everyone as it appeared from behind Hanger One.
Well, it was still a great sight to witness and document.
