I got one, and I'm kind of floating in the clouds at the moment.
My research area is in combustion, so it has direct applications to the military (particularly air force) - this most likely helped a lot.
I'm a first year grad student, undergrad GPA 4.0, GRE Q790, forget my V (~600?), W5.0, i had two secondary author conference posters, research experience in undergrad (and some graduate work), intern at NASA.
Thanks to everyone for advice/help/worrying together
