Vertibird signal grenade

The Vertibird signal grenade is a weapon in Fallout 4.

Characteristics
Soon after throwing a Vertibird signal grenade, a Vertibird will appear on the horizon and track towards the Sole Survivor and land in the vicinity of the marked location. The player character can then board the aircraft to take control of its side-mounted minigun. Opening the Pip-Boy map and selecting a location to fast travel to will cause the Vertibird to lift off and start flying to the selected location. When the Vertibird has landed, the player character may exit or use the Pip-Boy map to select a different destination. Alternatively, the player character can change the destination mid-flight. The Vertibird signal grenade can only be used outside, and only by members of the Brotherhood of Steel, the Minutemen or the Railroad upon completion of the former's main questline. The grenade produces orange smoke.

If the Sole Survivor completed the Railroad's main quest line, Drummer Boy in Railroad HQ after some time will say that the Vertibird is ready for use, gives the Sole Survivor 3 signal grenades then informs the player character that more of them can be purchased from Tinker Tom.
