When the line vans carry the crews to the flightline about 20 minutes in, one has rear doors closed. When the scene cuts, the rear doors are pegged open on both, which is correct for a hot climate base.
As the funeral party is leaving the base chapel, the firing party fires three volleys. Volleys are fired at graveside, at the end of the service.
Rivers is delivered a package at his hotel by a USAF sergeant, containing assignment orders and noting he's cleared of all responsibility for the incident. The review board would have told him personally and restored him to flight status, before he'd be eligible for a new unit assignment.
At the end, Rivers speculates about orders to Minot AFB, North Dakota. Minot was primarily a strategic missile and bomber base. It had a fighter squadron flying F-106 Delta Darts and as an F-4 pilot, he would not be assigned there without retraining.
