My Grandfather started flying for United, (PAT) in 1928. Unfortunately the Denver training center didn't exist. He use to fly a night mail run south in a Boeing 40B2/4. Different times.
Level Three His latest plane is a Cessna Citation X (0.92 Mach), which was the fastest bizjet ever built until the Gulfstream G650 was delivered in 2012 (0.925M). Naturally Cessna didn't want to lose their claim (fastest civil jet in the world once Concorde was retired for good) and the new Xs can do 0.935M. Arnold Palmer is extremely experienced and has 18,000 flying hours. He bought his Citation X in 2002.
