UPDATE: Five dead after two Alaskan flightseeing planes crash with cruise ship tourists aboard

KETCHIKAN, Alaska (KTUU) Five people are dead and one is still missing after a collision between two float planes with 16 combined people onboard, according to a cruise line whose passengers are among those killed.

Princess Cruises confirmed that both planes carried passengers from two Princess cruise ships.

A deHavilland Beaver, which Princess called an "independent" air tour, had five people onboard. Four were Royal Princess cruise passengers, and one was the pilot. Princess says all five confirmed fatalities were on that flight, the cruise line said in a statement.

The other plane, an Otter, was flown by local flightseeing operator Taquan Air. Ten passengers from the excursion sold through Princess, and a pilot, were onboard that plane. The plane was returning from a trip to the Misty Fjords National Monument.

Princess says nine guests from the Taquan Air plane have been rescued, and one;'s status is unknown.

Taquan Air says it has suspended all scheduled flights.

Princess Cruises says the Royal Princess is in the middle of a seven-day Voyage of the Glaciers cruise, which departed Vancouver on May 11, and is scheduled to arrive in Anchorage on Saturday.
