Black magic DOES work..

There's a Sod who does that around here, I keep quoting from one of
Spike Milligans books " I hope you Bloody well crash" but nothing has
happened yet. perhaps I ought to rip the page out
http://dev.epubbud.com/uploads/8/5/9..._Who___A_Confr
ontation_in_the_Desert___Spike_Milligan_epub/images_00036.jpg
and send it to the address the plane is registered at.
I'm sure if I revved a loud motorcycle around outside the chaps house
for hours he would complain but these Biggles types think it OK to
inflict their noise over a wide area. For some reason the aviation
hobby think planes and pilots are something special to be admired.
Maybe in the days of Alan Cobham and his flying Circus but the novelty
has long gone.

You'd think they'd have better silencers or at least silencers but it
seems that would cost too much for type approvals;!...

So I was told be a flying type..

I wouldn't be surprised if that wouldn't set a manufacturer back a
couple of million pounds, for something many users probably wouldn't
want to fit anyway. If it is a warbird, which are quite popular for
aerobatics, there might not even be a manufacturer still around to get
it approved.

A minor benefit of living on the edge of an airport control zone is
avoiding this sort of activity. Mind, you still get the plutocrats
helicoptering over to pick up their private jets.

Much quieter where the tail rotor is ducted.

Not on a soddin chinook or apache..

Dogs can hear em at 5 miles, and then they fly over at 200ft..

Although the discussion had moved on to light aircraft doing aerobatics
and, for those, most of the noise is engine noise.

Nope. Prop noise at least 50%

Yes we get those in deepest East Devon. A bloody nuisance, especially
when they circle.

The light aircraft are a pain too. I hear one crashed near Colyton the
other day, killing the sky-louse driving it. Good.

WEll having grown up on the approach path to the secret vickers airfield
I got used to V bombers at 50 feet where I were a lad.

And heathrow stuff as well.

But what irked me the last time I visited there before my parent got
terminally ill was te constant background noise from the....


....M25, now only 3 miles away.

Brooklands? I lived near there when I were now't but a lad and visited
a few times in the care of my next door neighbour who worked there. I
once saw Barnes Wallis at work in his raised-up office: something
taken over from the race-track days, I think, but was never allowed to
approach the great man.

At least most warbirds make a sound that has some character
and look reasonably interesting where as the modern thing that pesters
us sounds as pleasant as a chainsaw.

Get them just like that, mainly at night.
Had a sound in the house a few weeks back that was really bugging
me,turned out it was a light fitting being vibrated by Apaches. Could
not hear the machines themselves and it was a night or two later when
they came closer I noticed what was the cause . So that is now an
early warning device. But like the Hunters and Buccaneers etc that
used to suddenly wake the dead and make groggles **** themselves in
the Low flying area I once lived in the presence is fairly short and
exciting.
Unlike the aerobatic enthusiast who resembles a mechanical bluebottle.

I can hear the Chinooks inside at 5 miles ... Don't often get Apaches
over here. Don't like them they just look so damn mean and nasty as
they don't need to be streamlined.

and then they fly over at 200ft..

That high? The Chinooks are quite often below us or at 50' and just a
couple of hundred yards from the house. Half a dozen did that the
other year boy did the windows rattle...

The reason the Chinooks and other helos are so low, to keep out of
the way of the fast jets that come down the valley at just above our
level. At least the jets are up and past in less than 30 seconds.
There can be a good 45 degrees between where a jet is and where it
sounds it is.
