Unflown planes
Boeing 787 was rolled out on 8th of July, 2007. It was supposed to fly on 27th of August, 2007.
It has not flown.
Boeing 787 is supposed to be delayed by half a year. Once upon a time, Airbus 380 was supposed to be delayed by half a year, too. Then it was delayed again, by a year that time... but eventually A380 did enter service.
Dornier 728 was rolled out on 21st of March, 2002. It had 150 or so orders from respectable airlines like Lufthansa, and was supposed to fly and enter service.
It has not flown.
When would Boeing 787 fly? And would Boeing 787 fly, ever?
