I am pleased to announce that the first few of Allen Thomson's historical TLEs are available on my web page, at http://hea-www.harvard.edu/~jcm/space/elements They are in '1 line' format where the two lines have been concatenated with a letter N between them (don't ask why, that's how I got them). Enjoy! I hope Allen will be sending me more in the near future. Jonathan McDowell
