More than 300 flights were cancelled after a Japan Airlines (JAL) Airbus A350 carrying 379 people collided with a second plane while landing at Tokyo's Haneda airport.
The Tuesday evening incident forced the airport to shut down all runways for several hours late into the night, leading to cancellations of 226 flights to and from Haneda, affecting over 40,000 passengers, reports Xinhua news agency.
Despite the reopening of three runways on Wednesday, about 100 flights are still expected to be scrubbed on the day, disrupting the travel plans of 19,000 passengers.
At around 6 p.m.on Tuesday, JAL Flight 516, that had flown into the Tokyo from New Chitose Airport in Hokkaido prefecture was landing on Haneda's C-runway when the Coast Guard flight MA-722, a Bombardier Dash-8, collided with it, with both aircraft catching fire.
Television footage showed a large burst of fire erupting from the side of the JAL plane as it taxied on a runway. The area around the wing then caught fire.
The footage seen an hour later showed the blaze engulfed the aircraft.
Five of the six crew members aboard the MA-722 were confirmed dead, while the captain who managed to escape earlier was severely injured.
The Coast Guard plane, which belongs to the Haneda Airport base, was taxiing on the runway to transport relief goods for quake-hit areas in Niigata prefecture after a series of temblors of up to 7.6 magnitude struck central Japan on Monday afternoon, according to Coast Guard spokesperson Yoshinori Yanagishima.
Meanwhile, all 367 passengers and 12 crew members on board the JAL flight escaped from the airplane while it was on fire without life-threatening injuries after the collision.
The Tokyo Fire Department said it took more than eight hours to extinguish the fire following the crash.
A Haneda air traffic controller had permitted the passenger plane to land on a runway before the crash took place, and had ordered the Coast Guard aircraft to "hold short of the runway", national broadcaster NHK reported, citing sources with the Transport Ministry.
The Japan Transport Safety Board, the government-affiliated agency in charge of probing serious accidents involving airplanes, trains and ships, on Wednesday started investigating the cause of the accident and examining the aircraft wreckage.
