All the skinny on this aircraft is here.
After a disastrous, but highly educational, experience with its first Comet iteration, de Havilland has a 30-year success with this 4B.
Sleek aircraft, but there was some concern (from aircraft manufacturers who preferred engine pods) about the engines and the fuel tanks buried in the wings. Flew right well, though.
The card has been folded along its vertical axis. Still a good-looking card, I think.
