jees if one takes a negative stance to the responder one could read:
DEVELOP AND INHERENTLY SAFE BATTERY. (these lithiums are inherently unsafe)
A TEST METHOD TO ASSESS THE RESILIENCE TO THERMAL PROPAGATION OF A BATTERY SYSTEM (we have no idea what will happen if a cell explodes/ignites)
THEY DO. THE ESTIMATE IS APPROXIMATELY ONE EVERY TWO YEARS (the faa expects an aircraft every two years to be lost due to the risks of external fires setting the batteries off)
and lets not forget someone put the first design in the air the first place
i have to say i like the idea posted earlier about using the 787 for freight only for some time till they have seen how well the various fixes have stopped the fires
if they had so many problems initially it should be easy to see what differences exist due to the new design
i may be being a party pooper but with a bucketload of innocent lives on the line a little more caution than has been displayed recently seems to be not too much to ask
