SIR, - To your correspondent (Herts Advertiser, May 22) and others in Harpenden annoyed by the recent seemingly-endless east-west procession of Luton planes overhead, it is important to register your complaint with the airport management by phone on 01582 395382, fax on 01582 395500 or e-mail to noise@ltn.aero

Otherwise they may well presume our acquiescence with the increasing disturbance - for example the night noise profile is up 50 per cent over the last four years.
