Two work­ers were killed and an­oth­er se­ri­ous­ly in­jured in an ex­plo­sion Tues­day at a Delta Air Lines main­te­nance fa­cil­i­ty near the At­lanta air­port.

Delta said it was work­ing with lo­cal au­thor­i­ties to in­ves­ti­gate what hap­pened at the wheel and brake shop.

WSB-TV re­port­ed that a tire on a plane ex­plod­ed. The tele­vi­sion sta­tion cit­ed un­named sources.

Sev­er­al At­lanta fire units and po­lice re­spond­ed to the main­te­nance hangar near Harts­field-Jack­son At­lanta In­ter­na­tion­al Air­port short­ly af­ter 5 a.m., The At­lanta Jour­nal-Con­sti­tu­tion re­port­ed. Flights in­to and out of the air­port were not af­fect­ed.

“The Delta fam­i­ly is heart­bro­ken at the loss of two team mem­bers and the in­jury of an­oth­er fol­low­ing an in­ci­dent this morn­ing at the At­lanta Tech­ni­cal Op­er­a­tions Main­te­nance fa­cil­i­ty,” Delta said in a state­ment. “We have ex­tend­ed our full sup­port to fam­i­ly mem­bers and col­leagues dur­ing this in­cred­i­bly dif­fi­cult time.”

Delta thanked first re­spon­ders and med­ical teams.

“We are now work­ing with lo­cal au­thor­i­ties and con­duct­ing a full in­ves­ti­ga­tion to de­ter­mine what hap­pened,” the At­lanta-based air­line said.

The Fed­er­al Avi­a­tion Ad­min­is­tra­tion said it was in con­tact with Delta, but re­ferred a re­quest for ad­di­tion­al in­for­ma­tion about the ap­par­ent ac­ci­dent to the air­line. A spokesman for the fed­er­al Oc­cu­pa­tion­al Safe­ty and Health Ad­min­is­tra­tion, Er­ic Lucero, said the agency had start­ed an in­ves­ti­ga­tion.

The fa­cil­i­ty where the ex­plo­sion hap­pened is part of Delta TechOps, which per­forms main­te­nance, re­pair and over­haul work for Delta and more than 150 avi­a­tion and air­line cus­tomers around the world.

The pres­i­dent of TechOps, Delta Ex­ec­u­tive Vice Pres­i­dent John Laugh­ter, said in a note to staff that the air­line will make coun­selors avail­able to em­ploy­ees.

“We’re all in this to­geth­er, and we’ll get through this by sup­port­ing each oth­er,” he said.

At­lanta May­or An­dre Dick­ens post­ed on X to of­fer his con­do­lences to rel­a­tives of the vic­tims.

The In­ter­na­tion­al As­so­ci­a­tion of Ma­chin­ists and Aero­space Work­ers, which is try­ing to or­ga­nize 20,000 ground work­ers at large­ly nonunion Delta, called on the air­line and au­thor­i­ties “to quick­ly launch a thor­ough in­ves­ti­ga­tion in­to how this hap­pened.”
