Fly the Pelican or Phantom the the Campaign Mission New Alexandria
On the missions New Alexandria in campaign on normal or higher.
To do this you have have to complete the 3 objectives and when it says to defend the Oni building, you do what I do in the video.
If you want a Pelican drive a hornet through the building center, if you want a phantom drive a banshee though it.
If you exit them they WILL disappear.
People can ride in the back of the Pelican and the turrets of the phantom.
