There's been another drone incident raising concerns at an airport — this time in Saskatoon.

Transport Canada reported on an "unauthorized unmanned air vehicle" about six kilometres south of the city on July 1.

Saskatoon police reported that around 11 p.m. CST, the drone was flying over fireworks at an altitude of about 3,000 feet (914 metres).

The operator of the remotely-controlled flying device wasn't identified.

There was no harm done, but the drone incursion was noted by Transport Canada.

The federal regulator says there was "no operational impact" to the airport and no further action was required.

Another problem with a drone emerged in Regina a month ago when a pipeline patrol aircraft was in the air around the same time as a remotely controlled device operated by a film company.

Airport officials were initially unable to phone that drone operator, but later made contact and there were no further problems.
