Two Delta Air Lines employees died, and a third one was injured at one of the company’s maintenance facilities in Atlanta, Georgia. The incident occurred when a tire removed from a plane unexpectedly exploded at the facility’s wheel and brake shop, according to John Laughter, Chief of operations and president at Delta TechOps.

Laughter said, “I am deeply saddened to share that three TechOps team members were involved in an accident early morning in Atlanta TOC 3, Dept 391 – Wheel & Brake Shop. Tragically, two of our team members involved passed away, and one other team member was seriously injured. We are extending our full support to their families during this difficult time and investigating to determine what happened.”

The name of the injured employee was not released. The two employees who lost their lives are Mirko Marweg, 58, and Luis Aldarondo, 37. May their souls rest in peace.
