Two Vietnam Airlines planes collided while taxiing at Hanoi's Noi Bai International Airport on Thursday afternoon, grounding both aircraft and forcing hundreds of passengers to rebook. At around 2:23 p.m. on June 27, a Boeing 787-9 Dreamliner, registered as VN-A863, was taxiing to the runway for its flight to Ho Chi Minh City when its right wingtip clipped the tail of an Airbus A321, registered as VN-A338. The A321 was stationary, waiting to depart for Dien Bien, according to the Northern Airports Authority.
