It must be built so that the air-mass will sustain it and the motor, and the motor must be of sufficient power to overcome the air resistance. A ship ploughing through the waves presents the line of least resistance to the water and so is shaped somewhat like a fish, the natural denizen of that element. It is different with the aeroplane.
"We'd have gone through the effects of our own bomb with nothing more than a bad shaking of course, on contragravity, we're weightless relative to the air-mass, but she was built to stand the winds in the high latitudes. But the two geek bombs caught us off balance...." "You don't need to apologize, lieutenant.
No other art has ever made such progress in its early stages and every day witnesses an improvement. The air, though invisible to the eye, has mass and therefore offers resistance to all moving bodies. Therefore air-mass and air resistance are the first principles to be taken into consideration in the construction of an aeroplane.
