grammar fascist writes "CNN reports that Northrop Grumman is under contract to build a new supersonic, shape-shifting bomber by 2020. The main innovation is in its single, rotating wing. From the article: '[It] will cruise with its 200-foot-long wing perpendicular to its engines like a normal airplane. But just before the craft breaks the sound barrier, its single wing will swivel around 60 degrees (hence the name) so that one end points forward and the other back. This oblique configuration redistributes the shock waves that pile up in front of a plane at Mach speeds and cause drag. When the Switchblade returns to subsonic speeds, the wing will rotate back to perpendicular.'"
"Necessity is the mother of invention" is a silly proverb. "Necessity
is the mother of futile dodges" is much nearer the truth.
