The Air Force has always liked technical science degrees when it comes to people on paper, but at the end of a day in UPT, it's all about attitude (a good one), willingness to learn and stick/rudder skills. You could have an arts degree if you were born with the hand/eye coordination and mental capacity to operate an aircraft as a weapon system. Some people have to work at it more than others regardless of the degree they have. My suggestion is to get some flight time under your belt. If flying a Cessna 172 isn't for you, flying an F-16 or C-130 especially won't be for you.
Also realize the military isn't all about flying airplanes. You will be expected to perform duties totally unrelated to flying.
