We got some great shots on an AA777 from LAX to LHR. We were in F, so we boarded way early. We walked up and asked the FO (not sure where the Capt. was) if we could take some photos. I sat down in the left seat and my wife snapped a few photos. My wife noticed the Captain's hat hanging up in the cockpit and asked if she could put it on for her photo. He said "sure as long as you don't mind getting head lice!"

So she put on the hat and I snapped he photos.
We ended up with some very neat photos. That 777 flight deck is very cool.
