I think I can speak for most people here but, I watched the first 30 mins of Top Gun and went to a recruiter the next morning.
Nah but all jokes aside, my Dad started taking me to airshows when I was 5 years old and I instantly fell in love with aviation. It was always our thing, talking about planes, going to Air & Space museums, it's all I ever wanted to do. You could say I was obsessed. He tried talking me into joining the Academy and said he could help me get there but I never got serious about this career path until I was two years into my Bachelor's and after my Pops had already passed away. My whole family has served in the Navy... and after seeing my sister at her graduation ceremony, albeit she enlisted, I finally made the decision to contact a recruiter and follow my childhood dream of serving my country while flying bad ass planes that you will never get a chance to fly in any civilian aviation career.
