BirdAir was an airline owned by the construction company Bird & Sons, Inc which served in Southeast Asia during the Vietnam War.
Bird & Sons, Inc was a San Francisco heavy construction company operating in Vietnam and Laos that maintained its own air division.
Bird later sold the air division and its aircraft to Continental, $4.5 million cash, in 1964 to form CASI.
When that time expired, Bird got back into the air charter business and created BirdAir.
