ASPEN - The National Traffic and Safety Board said they are not ruling anything in or out as they begin the investigation into the deadly plane crash in Aspen Sunday.
Two men from Mexico are being treated for serious injuries. Another man was died in the crash. All three were pilots.
The plane went off the right side of the runway, flipped over and burst into flames.
Officials said the flight originated in Mexico and made a stop in Tucson before heading to Aspen.
The plane circled the airport multiple times before touching down, according to FlightAware.com. The airport is challenging for pilots because it is surrounded by mountains, forcing pilots to descend sharply.
According to witnesses and air traffic control recordings, the wind was very gusty at the time the midsized private jet attempted to land.
NTSB investigators have not had an opportunity to talk with either of the survivors who are in the hospital in Grand Junction. They also have not been able to get any video to watch of the crash itself.
The NTSB spent the day Monday making sure the flipped over, fuel-filled plane won't pose a danger to Investigators around it and inside it.
The Aspen airport remains closed. Airlines are busing travelers to the Denver and Grand Junction airports. Assistant aviation director Brian Grefe said about 3,000 travelers had been affected.
The airport may reopen Tuesday.
