Bombardier 415 flying boat / "water bomber"
The Bombardier 415 (formerly Canadair CL-415) water bomber is the only aircraft designed and built specifically for aerial firefighting. The 415 is a new-build improvement over the company's original CL-215 flying boat, featuring an improved structure, engines and avionics.
This aircraft (registry C-GOGZ) is operated by the Ontario Ministry of Natural Resources.
Here it is empty its load over a marker along the waterfront, fighting a simulated fire.
