As good a reason as any to invite one in! Convair 990?
Have see the odd exec 727 around in recent years, any still flying apart from the sprayers here? I get the impression most of the remaining flyers are hauling freight until they break or are wrecked in the parts of the world where propliners previously ruled the roost (other than North America!).
