Three people were injured in a helicopter crash in Antarctica this week according to NBC News.

The pilot had to make an emergency landing while coming back from a scientific mission to "survey a penguin colony" on Dec. 1. There were two passengers onboard the plane when the incident took place.

Australian officials said the helicopter crashed 170 statute miles short of the Antarctica's Davis station.

A second helicopter landed near the crash site and its crew tended to the injured people until medics arrived.

"We'll obviously obtain maintenance documentation in relation to the helicopter and information about the weather conditions and those types of things," Julian Walsh of the Australian Transport Safety Bureau said. "But until we know a little but more about the actual circumstances of the accident, it's a little bit difficult to actually determine the more detailed lines of inquiry that our investigation is likely to take."

Another aircraft was sent on Dec. 2 to find a place where a different rescue aircraft could land safety, according to CNN.

The pilot and passengers are "warm" and "well attended to" according to Australian Antarctic Division spokeswoman, who spoke with the Associated Press.

"Everyone's warm, everybody's well attended to, there's a field training officer who's got extensive wilderness first aid skills down there so they are very well attended to," according to the spokeswoman.

The temperature in Antarctica during December can get to around 0 degrees Celsius, according to the Australian Bureau of Meteorology.

The Australian Transport Safety Bureau is still investigating the crash.
