Officials say a plane carrying 42 people including a high school swim team went off the runway while landing at a small Alaska community on the Bering Sea.
The National Transportation Safety Board is sending a team of nine investigators to try to determine why a plane overran a runway when it was landing at an Aleutian Islands airport.
The NTSB said in a Twitter statement Friday that it was sending the team, following the incident Thursday.
Peninsula Airways says two passengers suffered critical injuries and 10 others were receiving medical care.
A high school swim team was also on the plane but a school official said team members were fine.
The plane was landing at the airport in Unalaska, which is home to Dutch Harbor. It is one of the nation’s busiest fishing ports.
