Or until you make a conscious decision to let this drug work itself out of your system through absolute abstinence. The wonder of flying is that it constantly generates new challenges to keep you ensnared. After the joy of your first our of airtime, comes the third stage. This is an extension of the previous, but ego and healthy competition now enters the scene, leaving you with the desire to be up the longest, watching your friends all sink out, then trying to stay up an hour in the most marginally light conditions, where only your obstinacy keeps you aloft. Then one day, you get everything right and climb to a height you never felt possible.
Earth truly becomes flat, mountains mere lines, the air crisp and blue as it bends around the earth.
Because from here, you have the power to glide to anywhere you wish. Airtime now is nothing. Even insignificant, as you cross horizon after horizon. This,the fourth stage of flying, is probably the most intense, and mother of the 300 km plus distances flown by the curnt spate of distance mongers. Places flat and arid become paradise.
