Last night BBC2; How safe are our skies?

The way carbon footprints are calculated are bollox.
The facts are:-
(new) Aircraft are in fact very efficient and per passenger mile more efficient than a single person in a most motorcars.

A motorcar with a driver and a passenger is more efficient than a bus.

A car with just a driver is more efficient than a train with only 25% full.

So lets ban cars and trains as well. Sorted.

One of these nutty, islamic jihad types only needs to get lucky once to blow 200 - 300 people out of the sky.

Or 700+, if it's one of those new super gigantic jobs.

Hmm, indeed, but I find the whole thing a little suspicious. The guy’s dad, who was well known and respected at the US Embassy in Lagos, warned the septics about his son. They had his name on lists of terror suspects but only did anything shortly before the plane arrived in Detroit.

Abdulunderpants supposedly studied engineering for some time; he should therefore have had the skills to figure out that his firecracker wouldn’t have caused much damage.

The news channels showed films of a supposed simulation of a similar device in aeroplanes; in those films a huge chunk of aeroplane was thrown into the nearby countryside and we were told that 80 grams of the explosive could have blown the plane out of the sky. In reality, 80 grams couldn’t cause much more damage than a flatulent Mexican.

Er, they did pop some rivets.

And that was more or less it.

Well alright, but it wasn't exactly a huge explosion.

[Mich the Tester]

I suppose it depends what it's 80gms of.

Pentaerythritol tetranitrate PETN in this case. V powerful explosive, but such a small amount wasn't really very impressive.
