There are many disadvantages of living in an urban environment that is constantly under video surveillance, and you all know how much I've talked about that. However there are some advantages and one has emerged. For the first time that I'm aware of, an ice fall has been caught on camera. These mysterious phenomena, known formally as "megacryometeors", are very rare, but they still happen regularly all over the world. One struck a lawn in
last year, see: https://hpanwo-voice.blogspot.co.uk/2017/09/another-ice-bomb.html.
Where they come from and how they form is not well understood, except their
structure is very different from hailstones or the lumps of ice that sometimes
fall from aircraft. This incident took place on a street corner in Kew,
London on the 9th of February. The
lump of ice strikes the pavement and shatters into pieces, startling passers-by.
Judging by the speed it is falling, it must have dropped from some considerable
height. Luckily nobody was hurt. I know of no instance where somebody has been
killed or injured by a megacryometeor, but several buildings have been damaged
by them. The media claim this has been proven to be a chunk of ice that fell
from off aircraft. It is true that the west London
sky houses the busiest airways in the world, but do we know for sure? Were any
of the ice fragments preserved and analyzed?
