With the M4 closed today, the lack of noise is very noticeable along a wide corridor going out to the Airport.It strikes me as being an ideal time (5 days?) to be monitoring noise from aircraft..and perhaps the Authorities should be grabbing this opportunity.At this moment here in Heston there is no noise for periods of some 60-90 secs...and then a roar as an aircraft departs these pleasant lands. The Motorway is asleep.
