I live in a village also regularly used by Chinooks for unlit night flights; a Top Tip, don't buy cheap Russian Youkon NVG's, mine packed up after 11.9 months !
I'm happy to hear or maybe see Chinooks or others training, but the local NIMBY parish rag mentioned ' menacing ' Chinooks at night; I've put Odiham ( who were very helpful ) onto them, with a bit of luck they are going to hold a presentation at the local hall.
