I was seeing the kicker in a winter
survival suit in my mind's eye,

Weather was nice. Body harness was for the kicker's peace of mind; he wasn't
an aviation type (at first).

Practice proved useful: Milkshakes are a no-go but Colorado Kool-ade did okay.
And the flight crew should wear goggles. Ash tray emptied itself as soon as we
opened the door and thirty years of trash suddenly reappeared :-)

Only real problem was to get the burgers there while they were still warm.
Trick was to start packing enroute to Brown Field. Had plenty of volunteers.
