Sophisticated bombs contained in packages sent from Yemen were designed to explode in the air and bring down the cargo planes carrying them, UK security officials have confirmed.Meantime Yemeni President Saleh is in damage control mode
Intelligence experts believe the use of the devices, contained in printer cartridges despatched on two Chicago-bound cargo planes, represents a shift in terrorist tactics to commercial targets.
Both devices, one discovered in the hold of a plane that landed at East Midlands airport after flying from Cologne, the other in a plane in Dubai, were described as "extremely professional" by intelligence officials.
One of the devices was linked to a mobile phone, while the other was attached to a timer. The Observer understands that the East Midlands device was so sophisticated an initial examination by forensics experts initially suggested it did not contain explosives.
"Even when it was examined, the sniffer dogs couldn't detect it," a security source said. "It was only when they [forensics experts] had a second look at it they realised what it was."[Emphasis mine..ed]
