Things like this make me feel old - I can remember when this aircraft first arrived. Same thing happened the other day, I was watching a trip report on youtube and they guy was taking a flight on United in their oldest 777-200 and I was working for Continental when that aircraft came in to take over from the DC-10's. The guy doing the report on youtube said he didnt mind flying on these old aircraft - 'historic' he called it..
Mind you I was at the RAF museum and one of the Harriers that I worked on in the 80's was parked inside - perhaps I'm historic!
