Yes indeed, Captain Airclues....the 749 at Marana is still flying, set to on tour during the summer, I believe. One more in the works there...for restoration.
IMHO...jet guys should stick to jets, unless they have the proper training for the 'ole piston slappers. It ain't difficult...but you just gotta know how....ahhhh, pistons! My favorite was the DC-6B...many happy memories.
