Hi Bernice

Determination is the most important factor and it seems like you have already taken care of that one :) Unfortunately you have to be a US Citizen to fly for the USAF. But what about flying for your own country ? Aren't you buying the Gripen ? I would love to fly that myself. It is a wonderful aircraft.
Keep the grades up and start flying gliders. That is the best prep you can do.

Regards RUN
