When John Glenn (here looking through a training device) became the first American to orbit Earth, a yaw thruster caused attitude control problems, so he flew the last leg manually. Half a century later, spaceflight still requires both automation and human skill.

The Astronaut Question

How long will humans remain better than robots at exploration?

Bell has built a Scorpion Too and an Executive, complete with trailer.

Half-breed: Piasecki Aircraft has taken a Sikorsky helicopter and bolted on airplane hardware — a propeller (ducted) and a fixed wing — hoping the resulting X-49A SpeedHawk (top) will bust through the constraints that have kept helicopters slow.

Hot-Rod Helicopters

There’s just no way to add 100 mph to the speed of a helicopter. Or is there?


One More Second

The masters of time are about to give us a little extra. Use it wisely.
