On that fuel burn, we saw 320 knots of true airspeed, or 368 miles per hour.

The color displays show the usual data--airspeed, climb rate, moving maps--and some new twists, such as graphic depiction of aircraft systems.

Once at cruising altitude I dialed in an economy fuel setting of 53 gallons per hour at a true airspeed of 390mph.

The 257-seat 7E7 can fly 9, 700 miles at an airspeed of 560mph.

Another knock-on effect of this extended journey time would see the dials and controls inside the craft lose power, leaving Allen to guess his altitude and airspeed.

Built from a box fan, medium-density fiberboard, lexan and aluminum, the tunnel increases airspeed by about 240 percent and cools its contents with a brisk 9 mph breeze.

But, back to the flying analogy, we see our airspeed slowing (economic indicators), we are already pretty close to the ground (recession), and our flight controls (policies) have been less responsive.

As the aircraft accelerates, the airspeed of a blade (and thus the amount of lift it provides) increases when that blade is moving forwards and decreases when it is moving backwards.
