Haha could have been. I did some research on it and I think it was from standing in one place too long. I was reading that If you stand in one place with your knees locked it can cut of circulation to your head. Its common in the military. Once I sat down (rather got picked up and set down) i was fine almost instantly it was very weird. It was a scary feeling. Now it's just more embarrassing than anything I bet those guys think I'm a wimp haha pass out while talking engines thats crazy who ever heard of such lol
