On 26 February 1988 he set his last indoor world record of 2.42 m in the in the Schöneberger sports hall, which was also as a special case recognised as the outdoor world record. In 1991 it was removed from the outdoor Wo rld Record lists, but it remained in the indoor world record lists (having been beaten by Javier Sotomayor in 1989 with a jump of 2.43 m). However, Thränhardt's mark of 2.42m still stands as the indoor european record.
Anybody know why is was regarded an outdoor WR at the time? Indoors is indoors, outdoors is outdoors? What "special case" was this?
