Well, I don't know, maybe they're all just a wee bit sensitive. I lived quarter of a mile from Heathrow for eighteen months, at whatever height that makes directly beneath (at least!) one major approach.
It was quiet (relatively) from about four in the morning till about quarter past.
Double glazing, plenty of sponsor's anaesthetic....we got used to it.
Maybe they're trying it on, or maybe they need to harden up.
