A Calgary family whose son died in a glider crash in 2019 is petitioning the federal government to do more to protect pilots and improve safety.

The crash occurred on May 13 near Gibbons, about 40 kilometres north of Edmonton.

OPP said that the incident happened on a private airstrip in the area of Concession Road 7 and County Road 1.

"Ken is a guy who is really well-known and really beloved in the air show industry," said his friend Mark Miller on Sunday.

The TSB report says despite repair work and inspections months before the derailment, the track subgrade remained unstable and was susceptible to "the effects of increased longitudinal forces produced by the high ambient temperatures."

Safety board investigators examined more than two metres of CN track that were recovered from the scene near the community of MacGregor, about 120 kilometres west of Winnipeg.
