    I searched for "glove" in the OIG Satellite Situation Report but did not
    find anything.
    I did find a screwdriver (#16013 1985-076H) lost on STS51I.  It remained in
    orbit for 6 months.  However, it appears that it was a large screwdriver.
    Reported radar cross section was 0.57 square meters.
