This is a very sad read.
What astonishes me even more is the document referred to in the report, the FAA/Transport Canada cargo aircraft fire risk model (
here (PDF)).
It seeks to predict statistically how many N-registered cargo aircraft will crash over the 10 years between 2012 and 2021, and how many of those crashes will be due to lithium batteries.
The report (see page 14) predicts about 6 crashes during this time (95% confidence interval is between 2 and 12 crashes). But what I find scariest is that it predicts that
of an average 6 crashes, 4 would be caused by lithium batteries in cargo.
