HOMESTEAD, Florida (AP) -- Two helicopters collided Sunday at the Homestead-Miami Speedway after the NASCAR championship, killing one pilot, authorities said.One helicopter was taking off from the speedway's helipad shortly before 9 p.m. while another was attempting to land, said Miami-Dade Fire-Rescue Battalion Chief Richard Martin."They had either a midair collision or a near-midair collision. One of them did a hard landing right on the helipad. No one on that craft was injured," Martin said.The other pilot died after being airlifted to a Miami hospital, a spokeswoman for the Miami-Dade Police Department said. The pilot's identification was being withheld pending family notification.Todd Shook, 46, of Sarasota said he saw the blades of one helicopter clip the body of the second helicopter, as he was walking to his RV parked outside the speedway.One helicopter landed lopsided on the speedway's helipad, and the other crashed into an RV parked nearby, he said."It just hit real hard, and then I saw the windshield all broken out," Shook said.It was not immediately clear if the RV was occupied at the time of the crash.Copyright 2005 The Associated Press.
