Vertibird plans

The Vertibird plans are a miscellaneous item in Fallout 2.

Background
The Brotherhood of Steel, the Shi, and the Hubologists all wanted the Chosen One to get these plans for them from Navarro, but it is unknown what his decision was. It is possible that he gave all three factions a copy of the plans, as the Brotherhood chose to repay him for the completion of the mission with his own copy and it's possible to steal them from either the Shi or the Hubologists.

Characteristics
They are a set of Enclave plans for building Vertibirds.

Locations
Found in Navarro inside a locker in the garage to the northeast, behind Quincy.
