There is no hard eveidence on the cause of the crash, or even any confirmation that lithium batteries were part of the cargo, yet everyone has jumped to the conclusion that lithium batteries were the cause.
To my knowledge there has not yet been an incident involving lithium batteries in cargo that were prepared in compliance with the regulations. All of the lithium battery incidents to date involving cargo shipments have been as a result of untested batteries or badly prepared packages where the battery terminals could short causing a fire.
So how about we wait to see what comes out of the investigation, or is that expecting too much??
