I flew N408BN from September 1974 until May 1982. It was technically not built for Braniff--it was a 727-291 having originally served with Frontier. Braniff employees could never figure out why they chose that particular 727 to have been painted by Calder unless it just happened to be the next one on the schedule to enter the paint shop at
DAL. Personally,, I would have picked a brand new ship --during that time period we were buying 727's about as fast as they could get them off the line at Renton.
Braniff pilots used to joke that Boeing must have dropped it on the assembly line as it always flew sideways--it was a very hard airplane to keep in trim.
I would add the two 747's leased from
LH--N610BN and N611BN (fondly known as "The Hindenburg" and "Hitler's Revenge.") Both were frequently down for nuisance items like inoperative galley equipment, popping circuit breakers, no movies, broken seats, etc
Northwest had two 747-135's they had purchased from
NA--N620US and N621US (known affectionately as "Laverne and Shirley" since
NA named all their airplanes after female employees. The biggest problems with those two were weird electrical issues in the cabin and very unreliable lavatories.
