Dangerous Winter Storm Friday Into Saturday
Currently, many roads and interstates are covered in snow and ice and have reduced visibilities due to blowing snow. Snow quickly moves out early Saturday morning and we start off the weekend with bitterly cold temperatures.
The plane belonged to Nature Air and had taken off nearby, according to authorities.
The reason for the crash is not yet known. They said the plane took a nose dive and crashed within minutes after takeoff.
"When I saw it sideways, I thought, 'Oh, is this a plane doing a trick?' I thought, and then I went, 'Wait, that's a big plane to do a trick, ' and then it".
The plane was believed to be carrying 10 passengers, at least five of whom shared the same last name, and two pilots.
