Do you know what happens with your suitcase in the airport behind the window with rubber cilia after registration?
Passengers leave their baggage when registered for a flight. A label is attached to a suitcase here, it contains information about an owner and his destination.
Oversized baggage may be checked in at a special check-in counter. Here fragile baggage is labeled as “glass” and sent down not on the common conveyor but on a special elevator.
The baggage compartment occupies a huge room looking like a small underground town under the airport. Its space is intertwined with a net of baggage conveyors which length is more than 3,5km. All suitcases are descending here on one of the 6 arms.
First of all the suitcase should be scanned. A scanner reads information on a label, so if you left a label with a bar code from a previous flight it may confuse the scanner and your baggage will go to additional handling where the needed label will be found by hand whereupon the suitcase will be sent to your flight.
Then the suitcase is checked by an introscope if it has any explosives, weapons or other prohibited articles inside.
A “suspicious” suitcase is sent to undergo more thorough check.
This check includes computer tomograph and diffraction.
Dogs are also used to search explosives.
