From George Tedbury
In your article on moon dust you reveal that Apollo 11, 12, 15 and 16 experienced poor visibility while landing (28 May, p 40). But we have photos of the feet of the lander standing on the lunar surface with not a speck of dust on them. If all the dust was blown away during the landing, Neil Armstrong’s historic first step would not have left an imprint. What are we to believe?
