By Annalisa Burgos Hawaii (KITV) — The Boeing 737-200 cargo plane operated by Transair that made an emergency water landing off the coast of western Oahu had only two people onboard and luckily no fatalities, but NTSB is treating this with the same gravity as if it was a passenger plane. They are sending in specialists.. their so called “Go Team”.. who will try to find out what caused the engine failure. The Hawaii Department of Transportation telling ABC News both engines failed. Aviation experts say that’s extremely rare. “This is a Boeing 737-200. This is an old airplane, it’s nearly 45-years-old,” said Tom Haueter, ABC News consultant and former NTSB Director of the Office of Aviation Safety. “The airplane should have been capable of coming back and landing on just one engine. So, there’s a lot of unknowns here.”
