The best source of information is IMHO not a news organization, but the corresponding authority, who issued the preliminary report.
The description of flight movement until the bitter end is fairly good, but
Why the accident really happened has not yet been published by GCAA.
The report by GCAA does mention Li-batteries in equipment (which are exempted from Dangerous Goods regulations due some very specific aspects) as well as Li-batteries which required a Class 9 classification (in plain English, undeclared hazmat).
There are more questions than answers to this preliminary report.
The positive aspect of this most unfortunate accident is that UPS aircraft will get a major upgrade in emergency equipment for the cockpit personnel (Fedex and other major cargo carriers already have this upgrade).
When you are monitoring all these incidents, you will come to a conclusion like:
- So far, no passenger aircraft hasd been lost due to Li-battery incidents (however there were some extremely close calls).
- Once this happens, the legislator (in the US and in other countries) will issue some serious modifications of HazMat regulations. Will it be for Air transport only? Or will it include Ground, Rail, Water too?
