The Civil Aviation Administration of Vietnam (CAAV) has revoked licenses of three air traffic staffers for neglecting their duties, resulting in an airplane almost crash into a truck as it was landing at the Noi Bai Airport in Hanoi last month.
A driver and his subordinate from the Northern Airports Corporation's Technical Services Company have also had their licenses withdrawn.
According to the CAAV, at around 4.17 p.m. on March 23 an airplane belonging to the FedEx Corporation was around 18 kilometers above the runway and about to land as instructed by the airport's control tower staff.
The pilots then saw a rubber removal truck running on the same runway, but managed to avoid the vehicle and land safely ten minutes later, it said.
Nguyen Van Chen, director of the Northern Region Air Traffic Services, where the three staffers worked, said his staff "forgot" to observe the runway.
It was a "rare" incident in Vietnam's aviation history, Chen said.
CAAV said the incident critically threatened aviation safety.
