Deep within the Underworld, the Deathlord Einherjar rules over a desert known as the Boneyard. It is said that whenever a plane crashes on Earth with no survivors, it will be soon be found half buried in the sand in the condition it was in before takeoff.
Einherjar has decided that these planes should be returned to service in the mortal world and can deliver them to you anywhere on Earth without hassle.
Given an annual budget in the single-digit billions, how can you get aircraft with extremely checkered pasts back into service? It's best if they fly routes similar to the ones they were lost on and for the carriers they originally flew for. Using magic is prohibited, as it's bad for your spiritual development to use the supernatural to do anything that can be accomplished mundanely. Commercial and law enforcement organizations in this world are highly corruptible, but it's imperative that the true origin of the aircraft stays secret.
For the familiar, assume that this takes place in the New World of Darkness.
