Raf Mona is just a landing strip which the student pilots use to practice take off/landings. It is purposely remote. Also it’s used most weekends by the flying club/ school, so the bloke must have known what he was moving to. I served at Valley for 3 years, we had loads of issues at the place. Until the dual carriageway was built the biggest problem in the area was ferry traffic hooning through the place!!
