Alf glances at the mess of piping, tubes, supports, and controls and can't help trying to make sense of what goes where, but is hampered by staying at the entrance way where he can maintain line of site on his illusion. Over the team channel he says "I don't much like the idea of hoping for the best, it doesn't usually work out well in my experience, but if any of you are thinking you might get inspired I can improve your chances by boosting your intuition. Given time I might figure out a spot, I know a tiny bit about machinery, but call that a last resort option."
Figuring that his focus is going to be needed elsewhere soon, he starts bringing his illusion down to ground, ninety degrees away from the road they came in on. Hopefully someone might think that is their escape plan and could send forces to cut off retreat in that direction, leaving their path clearer. Once he gets it low enough he has the helicopter turn out its lights and stop shooting, then after a few more seconds in the dark he lets the illusion go.
