Sunday marks the one year anniversary of the deadliest hot air balloon crash in U.S. history.
Sixteen people were killed near Lockhart located south of Austin after their hot air balloon struck a power line and went down.
Medical experts said the pilot, Alfred “Skip” Nichols, had been taking medications.
Among the victims, were Paige Brabson and her mother, Lorilee.
Eyewitness News talked to Patricia Morgan, the grandmother of Paige and mother of Lorilee.
"It's been a really tough year in our lives. We have struggled with the loss of both the girls. It's changed our lives tremendously. Right now, I turn everything over to God. I am thankful that I had the girls in the time that I did have them." Morgan said.
Morgan has fought for stricter federal safety regulations. Currently, hot air balloon pilots do not have to get drug tested or take medical exams.
She started a White House petition that eventually, caught the attention of Senator Ted Cruz. He filed a bill that would require balloon pilots to take medical exams.
"I believe the August voting will be to insert the certification requirements into the reauthorization bill. Then, the house has to vote on it," Morgan said. "Now I'm in a place where I'm fighting for the girls and the rest of the victims."
On Saturday, a vigil was held near the crash site in Lockhart. The crash remains under investigation by the National Transportation Safety Board.
