Great Scott !! How very odd indeed !! I'm not going mad.......
about 2 or 3 days ago, I was looking at the moon with a pair of binoculars. It was such a clear night, the moon looked great, it was a sort of cresent
moon, with the lower bit lit about north east, from where I was stood.
Venus was really close to the moon too, and really bright, the sky looked great. I saw a plane come out of the glow of the moon, ( roughly same
direction I assume) we get loads of planes flying over the house, its under the corridors that they use. ( south to north and north to south
There was something slightly off about this plane, it had a very slight yellow tinge to it, it didn't look abnormal, just not the same as I'm used
to seeing. It continued to fly sort of towards me, then kind of turned north, north west. As I looked at it with the binoculars, it sort of had a
goldy glow, plane headlight I assumed, then as it got more towards me, I could make out the red and white flashing lights as it started flying away
from me. 2 or 3 lights, close cluster, looked perfectly normal.
Then for a split second, there were about 10 to 20 red and white flashes, same as the others, looked, but they really jumped about in a random
pattern and sort of formed an edge around a rhombus shape that was seriously huge in the darkness. The original lights were still flashing as they
were before on the bottom left point of the rhombus. It took me by suprise and made my jaw drop. Then a few seconds later, it did it again.
I followed it with my binoculars as it headed off to the north east for as far as I could before it dissaperaed behind the houses / trees etc. It
didn't do the crazy flash again though.
I was baffled and logically concluded, that either my bioculars wobbled about and my brain made it into a patern or something, or, there was a
formaton of multiple planes flying without lights on with the plane, then flicked them on for a second. That's what I rationally came up with. But
as I perceived it, it really did look like an enourmous, dark rhombus shape, with crazy strobing red and white lights around the perimeter, that I saw
flash in random patterns twice. When I say enourmous, I mean big, very big. easily 50 to 100 times bigger than a plane and I'd say that was
conservative. I watched a few planes go over afterwards, so had a good sense of scale. I did hear a plane at the time, not sure if it was the one I
was watching, or another one close by, as I say, we get them flying over all the time. 4 or 5 in the sky at once is very common. There certainly
wasn't any more than one plane that I could hear though.
I'm about 5 miles south of Butser too !! I wasn't sure at the time, if it was my mind playing tricks on me, but your description sounded very
similar. Very odd indeed.
