KNOXVILLE, Iowa (AP) – Authorities say two men walked away after their aircraft plunged more than 500 feet before crashing near an airport in south-central Iowa.

The crash was reported about 1:45 p.m. Monday near the Knoxville Airport at Knoxville in Marion County. Jeff Jorgenson says he and pilot Miles Loomis had just taken off when their gyroplane stalled and began falling. Gyroplanes also are referred to as gyrocopters.

Jorgenson says the aircraft hit some power lines just before it struck the ground. He and Loomis were treated for minor injuries.

URBANDALE, Iowa (AP) – A man who worked for a suburban Des Moines school district for more than 11 years has been arrested on child pornography charges. Polk County Jail records say 28-year-old Justin Chugg remained in custody Tuesday on 10 counts related to the porn, including possession.

Urbandale Community School District spokeswoman Dena Soenke says Chugg worked for the district from August 2005 to Nov. 7 last year and was an Adventuretime leader. She says Chugg resigned after questions were raised about possible teenage drinking at his home. Urbandale Police Sgt. Chad Underwood says there’s no evidence Chugg had any inappropriate contact with any children.
