A man was killed when his home-built gyrocopter crashed just after he took off from the Lansing Municipal Airport in the south suburbs, officials say.
The Illinois State Police were called to the scene at 3331 Glenwood-Lansing Road in Lansing around 11:20 a.m., officials said.
The man was taken in critical condition to Munster Community Hospital in Indiana where he later died, according to police and the Lake County Coroner's office.
The man's name was not available pending notification of the man's family, officials said.
Wade Palmer, who owns Associated Air Activities at the airport, said two home-built gyrocopters took off from the airport and one of them crashed.
The two pilots are close friends and part of a gyrocopter club that operates at the airport. Gyrocopters are a combination of airplanes and helicopters.
John DeLaurentiis, manager of the airport, said gyrocopters are normally made from kits and are one-seat rotorcrafts with open-air cockpits that resemble small aircrafts.
"He belongs to a local gyrocopter club," he said of the pilot.
Airplane mechanic Paul Giebudowski said he saw two gyrocopters flying around Monday morning when one disappeared behind a building.
"He just went down, I thought maybe he landed. I never thought nothing of it," he said. "Ten minutes later all the (fire) trucks started coming through."
Before the crash, Giebudowski said the two pilots were "dancing" in their gyrocopters.
"They were just having fun," he said. "They were out enjoying themselves."
A National Transportation Safety Board investigator is arriving on scene, and will begin examining the aircraft today, a spokesman said. The NTSB has no preliminary information on the crash.
