Langley residents, RCMP, and local airport officials are trying to solve a minor mystery B次元官网网址� why did a plane circle the City for an hour after midnight late Friday and early Saturday?

On March 22 and 23, residents began calling the Langley RCMP about a plane that had been circling for some time.

There were multiple calls about the small aircraft, which was above Langley City for about an hour after midnight, said Cpl. Craig van Herk, a spokesperson for the Langley RCMP.

The Mounties checked in with NavCanada, which regulates aircraft and air traffic control towers in Canada, and determined that the NavCanada was aware of the craft, said van Herk.

B次元官网网址淭he actions were not illegal,B次元官网网址� so the RCMP closed the file, said van Herk.

The plane was apparently flying at 2,400 feet, van Herk said.

The Langley Regional AirportB次元官网网址檚 runway lights were off at the time, and airport manager Carol Madill said as far as she wasnB次元官网网址檛 aware of a plane taking off that late.

B次元官网网址淭hey should not have come from here,B次元官网网址� she said.

SheB次元官网网址檚 been looking into the matter after receiving multiple calls herself about the mystery plane.

The Pitt Meadows Airport did track the aircraft for part of its looping course, said Derek Brown, office services coordinator at the airport.

He said the aircraft was a Cessna 172 and it looped as far north as 80th Avenue at times.

After circling for a while, it headed off south and then east just after 1:10 a.m. on Saturday, March 23.

It didnB次元官网网址檛 come from Pitt Meadows either, said Brown.
