The National Transportation Safety Board (NTSB) said on Wednesday that it will open an investigation into a Jan. 23 runway incursion at Honolulu Airport that occurred when a United Boeing 777 crossed a runway and conflicted with a Cessna 208B landing on the same runway.

The Federal Aviation Administration (FAA), which is also investigating, said an air traffic controller told the United flight to stop on a taxiway before reaching the runway, but the United flight crossed it as the Cessna cargo plane was landing. The Cessna came to a stop about 1,170 feet from where the United jet was crossing, the FAA said. No damage or injuries were reported.
