(meteorobs) More on the Norwegian meteorite

We seem to be forgetting that a 'soft' object can expend nearly all of
its energy in the atmosphere.  For instance, the Tunguska object
expended far more energy than Hiroshima, yet NOTHING got to the ground
(except a shock wave, and maybe some dust).  

I suspect the fellow who was estimating the energy as comparable to
Hiroshima was basing it on the seismic data, and then only as an order
of magnitude estimate.

And re: multiple falls .... The published photo might have more than one
fall in it.  There's the obvious circular hole.  There may be a smaller
overlapping hole just below and to its left.  And then farther down and
a bit more to the left, is that debris from above, or is it a third hit?

Can anyone estimate the scale?  Is the hole 1 meter across or 30 m
across?  And that appears to be very solid rock. 

Any news of an expedition going to investigate?

Possibly this is a multiple fall, and more of this holes have to be
found.
And normally there is some exageration on this popular "reports".
Possibly the stones scatered into little pieces in the bush.
I would go there, if I could.
