A “fuse” with 2 kilos of HE? This is a firing device, meant to have enough punch to detonate much larger charges that need a good “kick,” including ANFO (ammonium nitrate/fuel oil), or artillery shells etc. IOW, terrorist bombs, such as IEDs.
Barometric sensor fuzes are a bad thang in a unpressurized cargo hold if they were built by the lowest bidder etc...
Or this was a blue badge noc noc effort.
