Here's a Canadian specialty you never knew about: We lead the world in the ability to mount a model helicopter on a model ship, spin the rotor really, really fast, and do accurate measurements of how the wind behaves.

At the National Research Council wind tunnel near the airport, the scale model helicopter and ship are showing test pilots what to expect when the Royal Canadian Navy gets a new ship next year.

The Interim Auxiliary Oiler Replenishment ship, a converted container vessel to be delivered in late 2017, will have hangars for two Cyclone helicopters, and a flight deck near the ship's stern.
