That's exactly what you get when you use Vidicon and Plumbicon tubes for imagers instead of modern solid state imagers. Myth - BUSTED. Let's do the math! Landing weight of LM: 30,000 lbs (4800lbs in the Moon's weaker gravity) Diameter of engine bell: 59 inches Area of engine bell: 2800 square inches Pressure on the ground at hover if the landing bell were flush with the ground (which it isn't) - 1.7psi That's about the pressure you can create in your mouth when you blow hard. Try to go outside and "blow a crater" with your mouth. I bet you'll just end up blowing some dust around (which is exactly what happened.) Myth - BUSTED. Did you skip high school math?
