A grass fire near Dallas/Fort Worth International Airport sent columns of smoke into the airspace near the airport Thursday evening.
The smoke was so high, planes approaching the landing strips at DFW Airport were flying through the smoke.
Fire crews from Hurst, Euless, Grapevine, Colleyville and DFW Airport worked more than five hours to contain the fire that burned roughly 15 acres.
Grapevine Fire Chief Mark Ashmead said the fire jumped the feeder road of State Highway 121 near Mustang Drive and kept burning in a wooded area.
"It's impossible to walk through. It's impossible to drive through with the brush trucks. We have to get heavy equipment in here to push down the small trees and saplings so we can get more equipment back in there to get to the scene of the fire," Ashmead said.
One Grapevine firefighter was taken to Baylor Grapevine for heat exhaustion, but will be fine.
The fire did burn through some power lines, but Oncor crews were working to restore power. As of 11 p.m. Thursday Oncor's website reported less than 50 customers were still without power.
Crews plan to spend the night near the fire to put out any hot spots.
