That device was small enough to be practical in an aircraft design, which we were ultimately able to build and fly.

Inside, advances in aircraft design mean no more stooping down in cramped, dark spaces.

And it did so with a style and panache that we seldom see in aircraft design.

A thin membrane could be incorporated into aircraft design to reduce engine noise for passengers.

These were used to support aircraft design, 'working out the stresses along the wings, and things like this'.
