It remains unclear why the plane was ordered out of the sky as the Ciambella and the RCMP offered conflicting stories.
Ciambella says he repeatedly checked with air traffic control to ensure that he was outside Ottawa’s restricted zones, and that at no time was he told that he had penetrated the restricted area above Parliament Hill.

RCMP spokeswoman Cpl. Lucy Shorey said officers on the ground spotted the plane and felt it was flying within restricted airspace over Parliament Hill

When the story first broke Monday, the RCMP directed all media inquiries to Nav Canada, the private company that provides air traffic control services in Canada.
But it confirmed the plane never breached a restricted fly zone in Ottawa and said its air traffic controllers never instructed the plane to land.
“We did not communicate that to the pilot,” said Nav Canada spokesman Ron Singer.
