Two employees of a Coral Gables glass company were hospitalized after scaffolding they were using fell as they worked at a Miami International Airport gate.

Juan Alvarez, believed to be in his 40s, and Anibal Amador, thought to be in his 60s, were working at gate D-9 on Concourse D in an area closed to passengers.

According to the owner of Coral Gables Glass and Mirror, Alvarez and Amador were attempting to repair a glass panel when the glass fell. That caused the scaffolding to collapse, and both men plummeted to the ground.

Both men were airlifted by Miami-Dade Fire Rescue to Jackson Memorial Hospital for treatment.

The hospital will not release the workers’ condition because Alvarez’s family has requested privacy. However, the victims appeared to be conscious, according to passengers who witnessed the accident.

“Someone came with a stretcher,” said passenger Hannah Blum, who said she and other passengers were caught completely off-guard.

“I got off the plane, and I saw this crash on the moving stairwell, and I was like, ‘Wow. What just happened?’” said Blum.

“There were a lot of people who were panicking, talking to police, saying something had fallen from the sky,” said Passenger Alex Davenport.

The cause of the accident is under investigation.
