Yes it is, I just got back from flying a few hours ago. I had issues with refractive error, but was able to get a waiver to fly after graduating from the US Air Force Academy. I had the privilege of flying three different fighters. I flew the F-4E, the F-111F during the first Gulf War, and the F-16. I flew for several years as an instructor pilot as well. The dream of going to pilot training was an answer to prayer, and only God could have made it happen.
