The Airpill logo is in fact a space pod. The space pod has a window (the circle), and is blasting flames out the rear end in order to propel itself into the stratosphere. Toward the moon, to infinity and beyond. Turned sideways, the logo looks like a pill, hence the name. So when you rock an Airpill logo, you're representing a lifestyle of blasting upward into the atmosphere, while eating air, with a smile on your face.
