Fifth and last test F-35B makes first test flight

The last Lockheed Martin F-35B development aircraft made its maiden flight on January 28, taking off from Naval Air Station Fort Worth Joint Reserve Base.

The STOVL jet, BF-5, has been assigned to developmental flight testing, and will ferry to NAS Patuxent River, Maryland, later this year, where it will join four other F-35Bs and one F-35C currently undergoing flight testing there.
