Sr. here. My third major mission, and Ms Wis' first big ride was on the U-2. As you can see from the certificates, we were flying more than 70,000 feet high in the U-2, also called "Dragon Lady". It was so high the pilot, Fats is his call sign, had to wear special equipment. A real space suit and oxygen so he could breathe.
To put it bluntly, this is normally a spy plane. The United States has flown it for years watching all kinds of things. If you look at the certificate you will see their moto, "IN GOD WE TRUST. ALL OTHERS WE MONITOR". Sounds like a pretty good moto for people doing that kind of work. Planes like the U-2s and the SR-71 have had a really interesting history in the ability of our country to keep track of what's going on around the world. There are some really good books about them. Check them out if you want an in depth explanation of these secretive planes.
We didn't go on any mission or anything scary. We just went up on a normal flight over California, or that general area, anyway. Once you get really high it's hard for me to tell where we are. But both Ms Wis and I really enjoyed the view and the opportunity to fly in this unique airplane. The other really interesting thing about our flight was that our pilot was number 911, meaning he was the 911th person to pilot a U-2 and he flew us on September 11, 1917.
