I too am an avionics enginner, now retired, and have worked with the F-111, F-16 and Tomahawk cruise missile through the tough times. Each had innovations and growing pains that we overcame despite the "It'll never work" handwringers.
I don't disagree that the solution may be dumping the LION batteries, I'm just tired of reading the "world is coming to an end" comments about the 787. It will fly again.
