When Milgrim opened the door, it swung out with an alarming, weight-driven velocity, to be stopped by a short pair of heavy nylon straps that prevented it from tearing itself off its hinges. He climbed down, with the red tube and his bag, briefly glimpsing the red tank of fire-extinguishing foam beneath the passenger seat, and tried to bump the door shut with his shoulder. "Ouch," he said. He put the bag down, tucked the tube under his arm, and used the other hand to heave the armored door shut.
