Twenty-one people were on board the MD-87 aircraft when it rolled through a fence and into a field where it caught fire.
"I happened to hear a boom and I looked back and the truck shook a little bit and I could see big orange flames up in smoke," Chelsea Alfaro said.
Alfaro was assisting with traffic as construction crews worked on a road near the crash scene.
"I didn't really see much of the plane go down but I did see the boom and I felt the explosion," she said.
Alfaro said she and her co-workers immediately started helping everyone and even assisted emergency crews with getting in and out.
The plane was headed to Boston for the American League Championship Series between the Red Sox and Astros, the plane owner's wife told KHOU 11.
