In living Life one will do a few things you regret.....and towards the end of one's Life the things you regret the most are the ones you wanted to do but did not.
Live your dream as best you can but remember not everyone that wants to be a Brain Surgeon becomes one.
Should the military flying thing not turn out.....find another way to soothe that itch you have to fly.
Despite a career flying airplanes and helicopters to include military flying.....I was the happiest soaring in a glider competing with Birds in a thermal column of rising air.
The next best was during flights in a hot air balloon floating across the countryside on a still Summer's Evening just as the Sun set.
