Martinez's Facebook Live video is mostly pixelated, showing him holding a phone with his oxygen mask band over his eye. Another video he took in the plane shows him breathing heavily with his oxygen mask as his eyes dart around.
Martinez told CNN he was sitting in a window seat two rows behind the busted window that nearly sucked a mother of two out of the plane. She was fatally injured.
"My thoughts and prayers are with her family," he said in a post on Facebook. "I feel very lucky to be alive."
