Operation Skyhook
this was the codename of Princess Leia Organa's mission to retrieve the plans of the first Death Star. The mission was predicated on an agent being able to steal the plans from a secret Imperial installation, a mission which was successfully completed by Kyle Katarn. Later, Leia was to travel to Toprawa and take custody of the plans herself. However, Imperial forces in the system forced her to change the plans, instead having the plans transmitted directly to her ship, the Tantive IV.
