I just learned about it today. The second Boeing 787 took it's first flight on Dec. 22:

It doesn't seem like there was much said about it at all. By the way, the gear got stuck in the up position and they had to do a 2.5G turn to get the gear down and locked! Shocked

So two safety critical systems failed then. Gear extension and manual extension Shocked

Where did you get this information?

I find it suspect in that they don't retract the gear on initial flights.

Don't argue with idiots, they drag you down to their level and beat you with experience.

They do retract the gear, just not immediately. Did that on the first first flight, just without the problems.

Perhaps the 2.5G turn was also part of the test program, to see if it was a possiblility in the event that all normal procedures failed. Personal experience has revealed it is recommended and works in a PA23 Aztec.

2.5G's quite a lot in an airliner. 1.5G's quite a lot too!

As Matt says, if it's true it's a little worrying!

Found an article about this flight.

Includes a couple audio files of air-to-air transmission between the 787 and the T-33.

Sixth Nightmareliner prototype flew, 4 months later than announced back in June (that on top of the delays of whole programme of course - if May 2008 was due date for EIS, what was the due date for all 6 prototypes flying?). The cause of delay is unknown. The maiden flight ended with emergency landing due to leaking cooling:

http://www.flightglobal.com/articles/2010/10/05/348122/sixth-and-final-787-test-...

Even if the prototypes can fly, the 6 prototypes have due to accumulation of changes and fixes so little in common with production frames that their tests cannot prove whether production frames can fly. Boeing needs to carry out flight test programme with two production frames, neither of which has yet flown.

The EIS due date of Genx 787 is unknown, as is launch customer (either Royal Air Maroc or Japan Airlines).
