Easterly winds / Heathrow

[toto]

Indeed Sue. Fifth day in a row without planes ! And still counting ! So nice and quiet :-)

Please Boris, build your estuary airport and it will be this quiet 70% of the year instead of 30% only.

Actually Boris airport was planned to be on the Isle of Grain, so no plane would overfly London (too far away). For Dulwich that would only leave the City Airport flights.

Sue, has the acoustic glass really made a difference? Was thinking of getting sashs double glazed with it but wasn't sure if it was one of these emperors new clothes things...

The sash window will vibrate if not installed correctly and snugly.

Take care.

It does seem to me to have made a difference.

I didn't actually get it because of plane noise (though that's an added bonus) but because of other noise from outside which was often keeping me awake and then waking me up in the morning.

However apparently a large amount of noise actually comes through gaps in sash windows, so just getting the glass replaced with acoustic glass probably wouldn't work unless you already have double glazed windows which are very tightly fitting.

I had a poorly fitting single glazed sash window.

But I probably need a few weeks to really be able to tell whether the new double glazed window with acoustic glass is making an ongoing difference. Ask me again then!

Personally I am sceptical of planes. This idea that the faster air underneath is enough to keep such large objects afloat seems farfetched.

[oilworker]

Actually the air is faster over the top of the wing which as a result of the Bernoulli effect gives rise to a lower pressure, hence lift. Fascinating things planes.

Yes. Don't you know they have to change the flight path so as to evenly distribute the chem-trails when a group becomes to self aware.
