Damage from explosion at a Beechcraft plant in east Wichita, Kansas.

A liquid nitrogen explosion at a Textron Aviation plant near Wichita, Kansas, injured 11 people on Friday, potentially setting back the introduction of a new aircraft under development, county and company officials said.

Emergency medical services took 11 people to the hospital, one of them suffering potentially serious injuries, Dr. John Gallagher, director of Sedgwick County EMS, told a news conference.

Injuries were limited because a skeleton crew was on duty during the holidays, said Deputy Chief Daniel Wegner of the Sedgwick County Fire Department.

The explosion in a 3-inch liquid nitrogen gas line also damaged a storage tank, causing nitrogen gas to vent out of the building, Wegner said.

News video from the scene showed what appeared to be a steam cloud billowing out of the damaged building. The gas was not harmful, Wegner said.
