Your brother is nothing if not efficient. In the front seat I see an american flag and at least one other flag. I have to imagine he took a few different shots that afternoon.
He took the same picture with a Boston University flag and emailed it to get on TV during the BU game. No luck, though.
The folded flags are kept folded. They are flown during a particular sortie then mailed home with a certificate mentioning what was done while that particular flag was inside the jet.
