Checkmate, aerodynamicists!

*Teardrop is not rain drop.
*rain drops alter their form continuously as they fall,as they are a deformable structure,yielding instantaneously to any stressor.
*A raindrops terminal velocity is meaningless unless its mass and time-averaged mean frontal area was specified as well as Reynolds number Same for human.
*The 'teardrop' is used in reference to streamline bodies of revolution of blunt nose and tapering tail.
*Streamline bodies are given the term due to the fact that they are 'streamlined',having no separated flow,and no appreciable turbulent wake.They are the lowest drag form for any structure tested.
