It's probably because they have their afterburners engaged. Makes a nasty noise (but it depends on the aircraft really). I used to live near an
airfield with F16's stationed there.
Sometimes they just fly low at high speed. Makes little children cry really.
 I do not live near Blackpool so I'm not familiar with any increase. Neither in the area I live by the way.
