Vertibird

Vertibirds are huge Enclave flying vehicles, a mix between a helicopter and an airplane. In 2241 one of them crashed near the trapper town of Klamath, and was the first sign of the Enclave encountered by the Chosen One. The Chosen One later stole the Vertibird Plans from the Navarro base, but it is not certain whether he gave them to the Brotherhood of Steel, the Shi, or simply kept them.

Appearances in games
