It’s been a tragic week for aviation as two military jets, a skydiving plane and a charter jet crashed over the course of just four days.

MIDDLEFIELD TOWNSHIP, Ohio — The Ohio State Highway Patrol is investigating a reported plane crash in Geauga County on Saturday. Troopers from the patrol’s Chardon Post responded to the scene in Middlefield Township, according to a brief statement released by authorities.

A series of aviation incidents has drawn national attention, with crashes involving a small business jet, a skydiving plane and two military jets.

Claude Guillemot, one of the five brothers who founded Ubisoft in 1986, reportedly died in a twin-engine plane crash in La Baule, France.

A small jet airplane crashed into a lake in West Milford Saturday evening, the FAA and local police said. Only the pilot was aboard the experimental amateur-built SubSonex JSX-2 during the 6 p.m. crash at Green Turtle Pond. He removed himself from the craft and refused medical attention, West Milford police Capt. Anthony Parello said.

A business jet with six on board crashed on a Laredo, Texas, highway and caught fire, killing one person and causing chaos as passersby frantically tried to save those inside.

The law firm had previously represented families in two other skydiving plane crashes in Missouri in Sullivan and Grain Valley.

Claude Guillemot died after a Cessna plane carrying the Ubisoft founder crashed on Friday in western France. He was 69.
