Why the F-35B is the most complex fighter in the F-35 family

The crash of a US Marine Corps F-35B fighter jet near San Diego has once again brought the aircraft into the spotlight. While officials work to determine what led to the crash, the incident has also renewed interest in the F-35B itself, a fighter that stands apart from the other two variants of the F-35 because of its ability to perform short takeoffs and vertical landings (STOVL).
