Hello everyone.I'm new here and just wanted to ask some questions on enlisted crewchiefs/aircrew in the USMC.I'm wondering if anyone can give me some idea of what it's like to be one and also how long/hard the schools to become one are.Also, what kind of stuff do they look for in a class II flight physical? I've heard that they disqualify lots of potential aircrew for even the slightest medical reasons.Thanks in advance for the replies!
