Mars (still in company with Mercury?) passed by the Earth at a distance of perhaps 40,000 miles -- well within Earth's plasmasphere. No shock would have been experienced then, only a continuous arc of lightning. (This is a rare case of [2] planets in relatively close proximity, and seems to have been so traumatic that "unconscious" archetypal imprints stirred to awakening briefly in the panicking public who tuned in to Orson Welles' radio drama "War of the Worlds" in October 1938.)
