In short, when I talk about bolides, I'm talking about any body

If it is a local definition, we can hardly expect NASA
explanations to match its properties.
Further, i gently suggest that to lump all 'objects
entering the atmosphere' together seems rather like
lumping apples and oranges, since they are both 'fruits'.
Or expecting a common set of behaviours from cats, elephants
and horses, which all have 4 legs and tails...

I suggest that the rapid (one might say explosive)

of producing the effects without electroacoustics.

They appear to come in a variety of sizes. And compositions.

The simulations indicate an airburst. An event some number of
miles high in the atmosphere. Any debris might well be
so small as to be not readily identifiable. If, for instance,
a cometary like object, the mass would 'boil' (an inexact term)

Large objects can completely vaporize. All that is needed is
enough energy. As from a fast, large, object.

time. Nikola Tesla and a freak bolide.
I fail to see the neccessity for an electroacoustic affect.
(Tho i cannot disprove them...)
One can calculate the energy in a range of sizes of
incoming objects. One can calculate the resultant 'explosion'
if such an object more or less completely disrupts due
to atmospheric drag. For certain, plausible, sizes and
speeds, the numbers match the estimated output, based on the
size of the flattened area. (I haven't doen the maths,

hitting the earth every year.
I'd say more like several thosand a day. Mostly ice.
Mostly unrecognized until 10 years ago, wehn someone picked
out there images in certain photos. NASA (et al) now
accept them. A strong case can be made that most of the
water on earth arrived this way. (Isotopic analysis...)
I've no idea if its relavent to the Tunguska Event.

Is NASA using it?

That's THAT event. Many differnt kinds of objects, with
different compositions arrive all the time. Comments from
NASA (or elsewhere) concerning any one event may not apply to

reports of an explosion, that bolides are relatively cold and don't
produce scorching heat.
Did NASA use the term bolide?
| ||They claim this object was likely 30 or more metric tons in mass and|
1 to 2 meters across, yet there were no sizable impact craters.
Is their any indication that the cornfield in PA involved
a re-entering object?

I know for a fact that either there would be clear signs
of debris or a very visible crater.
Others differ. Such like disintegrate, constantly, daily, high
in the atmosphere. (cf above. I've not got a nice web
refernce, but they are out there...). How much pf an
object arrives at gorund depends on what the mass,
composition and speed and angle of the arriving object are.

The real world is a fairly complex place, with a range of

I fail to see junk science here. Different events have
different causes. Differnt causes produce differnt

cf above on airburst. All may have arrived as fine dust.
[also cf below....]
cf previous [postings:
there ARE 'genetic anomalies' in the local plant life,
tho at a low enough rate that nuclear does not seem to be
involved and looking for specifically radiological
traces ('fallout') has yielded essentially nothing.
The low level anomalies are consistent with arrival of
low levels of random metals, etc, eg, the 'dirt' in
a dirty snowball (comet) or the residual bits of
either sort of metorite.
Also, it occurs to me, as i write this, that searches to
date have concentrated in the 'center'. Assume there
WAS an airburst. Assume there were some number of large
fragments. The aerodynamics of such, notably the
inertia, of such (if present) might well carry them
away from the center, indeed, out of the zone of
felled trees entirely. SOMEplace in Siberia MIGHT BE

for a thermal explosion, then the exploding bolide theory is in doubt.
Did NASA make such a statement ABOUT A HYPOTHETICAL Tunguska
object, or a probably smaller object associated with a
cornfield in PA?
Did NASA use the term biolide?

something created a freak electrostatic charge between the ionosphere
and the earth that resulted in a huge lightning bolt (just like the
ocean experiences huge waves called tsunamis, or the land experiences
huge waves called earthquakes.)
I suggest that the reentry of any of several classes of
natural objects account nidely. cf above.
| ||A huge lightning bolt could cause the above-ground explosion, leave no|
debris, make a sound heard for hundreds of miles, and provide a
streak of light in the sky.
Stretching for, literally, 100s, perhaps, thousands, of
miles (as the pre Tunguska sightings did?
| ||I grant that the large electrostatic charge may have been initiated|
by a bolide hitting the atmosphere under unusual conditions. Perhaps
the unusual conditions were in part created by Nikola Tesla.
I suggest, as above, that the entirely natural explanation
dependent on entering object also accounts, in a simpler manner,
for all effects.
Others propose other explanations.
