I remember reading about the 12-Apr-1999 case where two pallets of CR2 batteries. One pallet was damaged by a fork lift and it was some hours later that to caught fire and there was difficulty in putting it out.
This was after a pax flight from Japan and happened at the airport, but it just as well could have happen in the cargo bay.
What type of fire detection system was used on MH370, Ionization smoke, optical smoke, flame, high temperature, etc?
