An airbridge is the means by which an airhead is kept supplied by overflying enemy held territory.
The airbridge is used again by the new passengers to embark the aircraft.
An airlift over an airbridge can also be used when the most convenient means of transport is by air, or as an additional supplement to other forms of transport.
The passengers disembark using the airbridge.
