Patti Stringer like others in Weatherford still can't believe the news, that pilot Russell Haslam, flight nurse Adam Tebben, and medic Steven Fitzgerald are gone. The three died in a helicopter crash late Saturday night - after dropping off a patient in Oklahoma City.

"They're out to take care of everybody, they've taken care of someone's life and they're on their way home and something happens and they lose their own life, it just doesn't seem fair and doesn't seem right," said Stringer, a former Air Evac patient.

Lives like her own. She said an Air Evac crew helped her several years ago when doctors thought she was having a stroke.

The crew Saturday night was heading back to home base in Weatherford when the company said the control center lost contact with them. The helicopter crashed in Caddo County, less than 10 miles from Weatherford according to mayor mike brown.

The outpouring on Facebook is tremendous -- strangers, patients, and other first responders all united in prayers.
