Airbags in cars: Of crash sensors and rocket fuel

There's the squeal of tyres, the crash of breaking glass, and then the airbag immediately inflates. The now ubiquitous safety device that protects the head and upper body in a car crash first made its appearance in vehicles half a century ago.

This is how it works: sensors register a collision and trigger a propellant charge that causes a textile bag to instantly inflate with compressed air, cushioning the head.
