Talking of "bombing" from a Shackleton....
8 Sqn pulled the same stunt on us (except we had the brains to do our dinghy drill in Cyprus) - the impromptu solution to prevent further risk of bombing after the first drop was to use our miniflares as SAMs. Quite effective, as we found out at Animal House afterwards - at least a couple of hits. Nice to give them a taste of their own medicine.
