Wind Tunnel for Airplane Tests (and Tea Trays?) Research experts of Canada's national research council test models of new-type planes in new wind tunnels that blow bugs out of future aircraft. Various shots inside the Canadian lab with Wind Tunnel setup, model of plane placed in tunnel; technicians watch from above, standing behind rail around the circular top opening of the tunnel. Shots of crews at display of gauges. A model plane is thrown into an artificial wind vortex to test how to help planes resist spins? (but it spins alot!) A funny bit where a technician standing at the rail accidentally lets his tea tray slip away from him and it is held in mid-air suspended by the flow of air coming up from the tunnel. Various shots as the man chases the runaway floating tray back and forth, leaning out over the rail making unsuccessful grabs at it. Very humorous.
