I am totally amazed that in today's speculative press, the obvious potential for a connection between the UPS crash and the recent events with bombs on board freighters has not been made so far.
Several posts raising that possibility, including mine, have been removed. Maybe that's one of the many PPRuNe taboos...
The GCAA points out there was no audible CVR indication of an initial onboard explosion on UPS 6 but as the Times Square bombing recently showed, a dud bomb can start a fire instead.
I don't claim to know the answer as to whether the UPS aircraft events are related but the coincidence is certainly unusual.
