From: Rick McGeer (on an aaa-60-s) <mcgeer%ucbkim@Berkeley> Sorry, the last line of my message should have read: "in short, it is true that a gas molecule at STP is longer than the wavelength of any solar radiation, and hence holes in light sales will reduce drag without affecting thrust, if the holes have diameter less than 250 Angstroms."
