I would hardly call MK's fleet modern! Regardless of that Manstonman, sadly the argument 'we were here first' does not stand up in under UK law!
People have a right to live in homes without too much invasion from noise pollution etc. You would be pissed if you moved into a house and the next door neighbour played music loudly and his response to your complaints was simply 'i lived here first.' Every airport in the country is having problems like these!
