I crewed an honor flight several years ago. Awesome flight and it was a thrill and an privilege to skipper the flight.
Since it was a transcon IAD to SFO, we had a quick chat with the group leader to check on special needs. There was a flight nurse on our trip and the company put on extra O2 bottles just in case (none used). Flight went very smoothly, these 90 year old guys were in mostly good condition. Gave lots of before & after cockpit tours and met a guy with a flight jacket on with the name "lucky". He was enlisted in WW2, F86 fighter jock in Korea and a commander in Viet Nam. He sure earned the name!
We got a water canon salute on arrival and had a great time. Enjoy the trip.
