Vertibird signal grenade

The Vertibird signal grenade is a weapon in Fallout 4.

Characteristics
When the grenade is thrown in an appropriate area, a Vertibird will appear in the distance and head towards the player's location. The Vertibird will land at or near where the grenade was thrown. The Sole Survivor can then board the aircraft and take control of its side-mounted minigun. The player then chooses a location on the Pip-Boy's map and the Vertibird takes off and fly's to the selected location. When the Vertibird has landed the player can either exit the aircraft or use the Pip-Boy’s map to select a new destination.

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.

Variants

 * The Minutemen have two similar support items, flares and Artillery smoke grenades. The flare will signal for troops and the smoke grenades direct a strike from nearby artillery.
 * The Institute have synth relay grenades to spawn synths.

Locations
First given by Elder Maxson as a reward for the quest Show No Mercy. More can be bought from Proctor Teagan aboard the Prydwen or from Tinker Tom at the Railroad HQ after finishing the main questline for the Railroad.

Bugs

 * When choosing a location to travel in the Pip-boy map, a location can't be selected and a message stating that you can't fast travel while falling or jumping appears.
