Interesting you should make a comparison with the Comet - another jet with oversized windows. Hope that's not a bad omen!
IIRC it was the windows on the Comet that were too big and the aircraft couldn't cope with the repeated pressurisation/depresserisation, although I'm sure this won't be a problem on the 787.

As to the 787, that will be for generations beyond mine to determine.

However, the certification process is just huge for these sort of products on civil aircraft and even more so for ETOPS flights so the amount of testing and result submissions and risk assessments already carried would have been massive.
I do believe the A380 uses them too but am not 100% sure...

Glad to hear it, always makes me think when one particular aircraft continually has problems....also glad to hear BA going to wait for 100 787 & 380's to roll off the line first. ^

There have now been a number of electrical related faults and fuel leaks across a number of different aircraft now. Admittedly the sample size is still quite small but it would appear some resemblance of a pattern is emerging. I so hope not though

I presume with the B787 it is necessary to start the APU inflight in the case of an engine or generator failure,which is not a requirement for the A380.If that is the case,and the APU battery has a fault that risks a fire on startup,that could prove very difficult for ETOPS approval.
It would be very unpleasant to have a battery fire mid pacific.

In flight, if three or more engine generators go offline, the APU automatically starts, regardless of APU selector position. When the automatic start condition is no longer valid, the APU can be shut down by positioning the selector to ON, then OFF. When the automatic start condition is valid, the APU can only be shut down by pulling the APU fire switch.

Im sorry I wasnt being 100% serious with my comments.
But if we do end up seeing further delays to the 787 deliveries I would expect BA to see some further compo from Boeing in respect of the delays, I wouldnt be surprised to see the 7 x 763s that are scheduled not to have the spruce up actually end up getting it and as such staying in the fleet for longer than we were expecting.
Just my thoughts being thrown out there
