Hi Chris and Gary:
Comets can be "hot" (actually warm) relative to the ices in them, so we
are still talking about temperatures well below the melting point of
water, at least at the distance of the Earth. Even though the ices, when
mixed with dark material (carbon, for example) could potentially
Sorry, but that's just crazy. A meteoritic body that strikes the ground
at terminal velocity, as virtually all meteorites do, cannot be hot
enough to start a fire. It doesn't matter what it's made of. And in
fact, there is virtually no evidence supporting the idea that cometary
bodies produce m

No, Gary, during the dark flight phase, a meteoroid cools
sufficiently to not incite a fire. Meteorites may be hot to the
touch but not hot enough
If the meteorite is a comet fragment, then there's no reason it can't be hot
enough upon impact to start a fire under the right conditions. Recent
evidence has shown that some comets are hot and dry not icy and some also
have gas jets on their night sides which astronomers have theorized is only

The first and last examples are highly speculative, and probably not
examples of fires started by meteorites.
Tunguska, of course, shows how fires can be started by the air burst of
a _meteor_, which makes sense. But I don't know of any case where there
is good evidence of a fire started by an
Some meteorite in Africa, if I remember (don´t remember this hammers

That's like saying guilty by association or proximity. If you're walking by
a crime scene as the crime is in progress, this in no way implies you're a
suspect. It's a coincidence. Same with the suspected super bolide fires.
Just because fires start during a bolide sighting, it in no way implies
There is NO suspicion at all that any Colorado fires were connected with
meteors. During one fire, controllers rather foolishly grounded the fire
fighting planes after witnesses reported a daytime fireball over the
eastern part of the state. That's the extent of it. Everything else is

Now- those are good questions.
I vote yes to both---?

I've never heard a credible account of a fire started by a meteorite
fall, and on theoretical grounds, there's no reason we would ever expect
a meteorite to be hot enough to start a fire. Of course, that doesn't
discount a secondary effect, such as a meteorite causing a fire by

No, it's never happened, it's impossible. I wish people would stop saying

Hello all,
I am investigating a case here in Brazil where something has fallen from the

Witnesses heared a loud buzz and soon noticed smoke and fire on a nearby
mountain. Some work have been done on the
local by the fire department and nothing was found rel
