I am not sure what these are, but I just saw a group of 4 take off in formation, and then two sets of two take off. I must say that the airport today has seen a very heavy miltary traffic. I have uploaded a video of them taking off to youtube, which you can see below as soon as its done converting.
Also as you might have guessed, I am flying somewhere. I am flying up to Columubs, OH for my sisters graduation. As much as I would love to update more, I need to go catch my flight to DFW (which is ontime), then about an hour on the ground there and then its off to Columbus.
