BBC NEWS | UK | Detonation of liquid explosives
This video shows the damage caused by a liquid bomb to a commercial airliner.
The BBC used a qualified explosives engineer, Sidney Alford, to construct the devices to demonstrate their likely effect on an aircraft fuselage.
I am quite surprised – I didn’t think there was anything at all in this security idea that you can’t take liquids onto a plane. I suppose my next question is “does limiting to a clear bag full of liquids actually stop the risk?”
