At the moment, if you transport liquids in your hand luggage, you have to follow a few rules. The containers may have a maximum capacity of 100ml and they have to be stored in a transparent plastic bag with a maximum capacity of one liter. But that could soon be over - at least at some airports!
Computer tomography scanners (CT scanners) are currently being trialed at Heathrow, Gatwick, and Birmingham. These create three-dimensional views of the luggage (rather than 2D pictures, which are common at most airports around the world). The change to 3D technology means no more need to minimise the amount of liquid carried or to separate electronics from the rest of a traveler's luggage.
This not only brings direct advantages for travelers, who then no longer have to fetch liquids from their hand luggage and can take larger containers and thus drinks through the security check. This should also lead to fewer delays.
According to media reports other European countries are looking into introducing similar technologies.
