Five people are dead and one person is unaccounted for after two floatplanes carrying passengers from a cruise excursion collided mid-air in Alaska.

The two planes carried 14 passengers from a seven-day roundtrip cruise out of Vancouver, according to a statement Monday from Royal Princess Cruises. Both planes collided mid-air about eight nautical miles from Ketchikan, Alaska, at the southeastern end of the state at about 1 p.m. local time.

“We are incredibly distressed by this situation, and our thoughts and prayers are with those onboard the planes and their families,” the cruise company said. “Princess Cruises is extending its full support to traveling companions of the guests involved.”
