Time to end the speed limit in US airspace?
The faster the plane goes, the more fuel it consumes due to the drag increase by the square of the speed. In a world where fossil fuel is needed to fly airplanes and where oil is causing a destruction of the world we inhabit, it's dangerous to suggest we should make the flying industry polluting more than they already are.<p>If anything we should look at the trade-off benefits of flying with the least amount of fuel consumption per passenger and miles flown. Flying faster than mach-1 to save time will be reserved to a small elite. How does it benefit the masses?
