(a) I’ve seen a test on an exploding lithium battery, you don’t want that on an aircraft.
(b) The batteries that brought the A/c down (Mentioned above) were massive industrial batteries, one of which caught fire in the hold because a trip switch on the side of it had been left off, and the boxes were also incorrectly marked as discharged, when in fact they were fully charged.
(c) Pistachio nuts can be classed as an explosive, they will be next 🙂
