Nikki Walker looked like he would add a second break-out try for the Ospreys, sent away after fine work by Andrew Bishop, only for his Scotland team-mate Sean Lamont to drag the wing down.

In between, Glasgow had almost stunned the home side after Sean Lamont intercepted a Jenkins pass on his own 22 and raced upfield, only for Aisea Havili to drag the wing down short of the Warriors line.

Nuthall managed to drag down the 6ft 2in, 15st wing but Glasgow skipper Mather was on his shoulder to dive over.

The company said it would be focussing on the design and manufacturing processes needed to produce a next generation composite wing, with the emphasis on reducing weight and aerodynamic drag.

Unfortunately, because of the nature of air circulation, any downward-pointing force created aerodynamically generates a backward-pointing resistance in the process just as an increase in the lift of an aircraft wing as the flaps are lowered for take-off or landing creates more drag in the process, forcing the pilot to open the engine throttles to overcome the extra wind resistance.
