English: The Comer family in the passenger terminal at Travis Air Force Base, Calif., wait to board a bus that will take them to an awaiting C-5 Galaxy heading to Hickam Air Force Base, Hawaii, on April 17. The family is making their way back to Kadena Air Base, Japan where they are stationed. Knowing some military aircraft are noisy inside, they have headsets for the smallest boys and earplugs for the others. This family used their "space available" air travel privilege to fly on what is primarily a cargo flight. The privilege of traveling on these flights come with positives such as zero air fare and negatives such as flight times that are set to support operational mission needs and movement of cargo and seating ranges from commercial airline seats to fold-out web bench seats. And most military aircraft do not have as much sound insulation as commercial airliners. Travis Air Force Base's 60th, 44th, 55th, and 82nd Aerial Port Squadrons operates AMC's primary west coast aerial port. They support seven U.S. Air Force major commands, Dept of Homeland Security, and all DoD services' air transportation needs with a budget of $4.8 million. More than 530 assigned personnel support traffic management services, passenger/cargo movement on airlift missions maintaining a global deployment capability for the largest wing in AMC.
