A previous example is the 1972 fireball observed over Utah, Montana
and Alberta, but this body never came closer than about 57 km from the
Earth and was much smaller (say 5-15 m or so) than the one
hypothesized here. The 1972 object produced sonic booms but no damage.
It was observed by many and actually filmed. My wife saw it. So, the
new hypothesis about Tunguska should be taken seriously and not
dismissed out of hand.
