Who on earth thought of using these batteries? I thought we couldn't check them in our hold luggage, something about them being too dangerous. And I thought they have brought down a couple of cargo 747's, although I could have that wrong and would happily be corrected. What is more, why are the airlines so happy to take an aircraft with them in the first place? It is all very well blaming Boeing and the FAA as some are in some threads and in the media but surely airlines are aware of the dangers in these batteries. They should have said no to the aircraft. I certainly will until this is sorted.
