In Boeing's view, neither incident met the company's internal definition for the condition called "thermal runaway". That is a situation in which there "is so much energy, so much heat and so much flame that it would put the airplane at risk", Sinnett says. "We know very clearly this was not the case in the Logan event and the Takamatsu event."
Wow, I hope Sinnett didn't take that attitude with either the Japanese regulators or his customers, at least until after a deep bow and an apology.
