During the Dallas Air Show, two planes collide and crash.

During a Dallas air show on Saturday, two ancient military jets collided and plummeted to the ground, bursting into a ball of flame and sending plumes of black smoke pouring into the sky. It was unknown how many individuals were on board the plane or whether anyone on the ground was injured.

Anthony Montoya saw the collision of the two planes.

"All I did was stand there." "I was in full shock and astonishment," said Montoya, 27, who was with a buddy at the air show. "Everyone in the room was gasping. Everyone was sobbing uncontrollably. "Everyone was taken aback."

Emergency teams rushed to the accident site at Dallas Executive Airport, which is around 10 miles (16 kilometers) from downtown Dallas.

Live TV news video from the scene showed people erecting orange cones around the bomber's crumpled wreckage, which was located in a grassy location.

"The videos are terrible," Dallas Mayor Eric Johnson posted on Twitter, adding that the National Transportation Safety Board has taken responsibility of the disaster scene, with assistance from local police and fire.

The Boeing B-17 Flying Fortress and a Bell P-63 Kingcobra collided and crashed approximately 1:20 p.m., according to the Federal Aviation Administration. The accident happened during the Commemorative Air Force Wings Over Dallas display.

The B-17, a massive four-engine bomber, was a cornerstone of American air supremacy during WWII. During the battle, Soviet troops mostly deployed the Kingcobra, a US fighter jet. According to Boeing, most B-17s were dismantled after the conclusion of WWII, and just a few exist today, mostly on display at museums and air shows.

Several videos released on Twitter showed the fighter jet flying into the bomber, forcing both to fall to the ground and igniting a big ball of flames and smoke.

"It was just awful to witness," said Aubrey Anne Young, 37, of Leander, Texas, who witnessed the incident. Her children were with their father inside the hangar when everything happened. "I'm still trying to figure things out."

On a video Young posted on her Facebook page, a lady next to her can be heard crying and screaming frantically.

For years, air show safety has been an issue, particularly with older military aircraft. In 2011, a P-51 Mustang crashed into spectators in Reno, Nevada, killing 11 people. A bomber crashed in Hartford, Connecticut, in 2019, killing seven people. The NTSB stated at the time that it has reviewed 21 incidents involving World War II-era bombers since 1982, resulting in 23 deaths.

According to the event's website, Wings Over Dallas describes itself as "America's Premier World War II Airshow." The display was slated during Veterans Day weekend, Nov. 11-13, and spectators were expected to witness more than 40 World War II-era aircraft. Saturday afternoon flying displays included a "bomber parade" and "fighter escorts" with the B-17 and P-63.

Wings Over Dallas videos show vintage aircraft flying low, often in tight formation, on simulated strafing or bombing missions. The planes are also shown executing aerobatic maneuvers in the footage.

Officials claimed the FAA was also conducting an inquiry.
