My father was an F-4 pilot in the '80s, he absolutely loves that plane. It stung him a bit when he saw one up on a stick when he came to see me at Lackland.

I don't have a question, I just think the SR-71 is an awesome plane, thanks for the ama!

How much of the erosion on Mars do you think was caused by the melting cycle of dry ice deposits as opposed actual liquid water?

Oh that is cool. Thank you!
