US Air Force Museum 6

Here is brother Davit (aka David) who knows tons of plane ephemera and who, indeed, used to volunteer at the museum. He's full o' lore, such as this re: the U2 spy plane - at cruising/spying altitude, the plane had to be kept with in a 10mph window, else either a.) the engine would stall out or b.) the wings would fly off. Whoot! He's full of that stuff!

He does not have an answer as to why the band U2 would do such cloying treacle as "Who's Gonna Ride Your Wild Horses?," however.
