Touched down is a term used to describe when an aircraft or other vehicle has arrived at its destination. The term can be broken down into three parts: LIT (3 letters), ALIT (4 letters), and LANDED (6 letters). LIT stands for 'LANDED in Transit, ' which means that the aircraft has LANDED but is still in transit. ALIT stands for 'Airborne Landing in Transit, ' which means that the aircraft has LANDED while still in the air. Finally, LANDED means that the aircraft has arrived at its destination.
