Sorry-Been off spearing

2 x Trevally, 5kg and 8 KG and will return tomorrow if the weather holds!
Sinkweight, you are very correct and I should have mentioned that while the inside of the aircraft was pressurized, the outside was not. My point was more towards a lighter attack
As far as the C4 being used, as someone who has used C4 and other things to blow up a lot of things from vehicles to buildings to aircraft (pieces), if I place a charge carefully in the right place, it will cause great damage, if I have C4 in my shoe(i.e.; not a carefully placed charge), it will likely blow my feet off. I am not a structural engineer but I think the cargo area is different (structurally) than the passenger areas...BTW I lived within a 2 minute walk of the Ottobrunn facility for 3 years-some REAL COOL tests done there! Especially with wierd helicopters
Anyway, as others have said, Terrorists bad, aircraft not-so-bad.
