Vertical Envelopment Question

[Death Scream]

I have a question regarding the Vertical Envelopment achievement. If you are playing the last mission in campaign co-op with three other people and you enter the helicopter to fly to the landing zone co-ordinates,but you are not the pilot and one of the other people in your group is. Does everyone get the achievement when the helicopter lands at the LZ or just the pilot? And will it unlock if you create a single mission co-op?

That would be yes everyone and a yes to those questions. When the achievement has the word "Fireteam" in it everyone gets the achievement. :locked

Ok,but the achievement doesn't have "fireteam" in it. So all I want to know is can you get the vertical envelopment achievement if you let someone else fly the helicopter your in to the landing zone with the purple smoke?
