Katy Austin, for the BBC:

Passengers at Britain’s biggest airport, Heathrow, can leave liquids in containers up to two litres in their bags while going through security, after it finally completed the rollout of new high-tech CT scanners.

Electronics such as laptops can also be left in luggage, while clear plastic bags for liquids no longer have to be used.

Heathrow now says it is the biggest airport in the world to have the new equipment fully rolled out across all its terminals.

Hooray for the HI-SCAN 6040 CTiX.
