A colleague has a house that overlooks Chivenor and his son is an aviation spotter - he told his dad what the Chinook was doing.
You can start with name calling if it makes you feel clever but the Catterick crash started with 'high spirits' and 'interesting flying manoeuvres' and ended in tragedy. If the lessons still haven't been learned and the wire strike was the same flight as the one my mate's lad saw then getting it out there is the best thing to do to prevent another poorly disciplined crew taking other people with them.
It may not have been connected with the wire-strike flight at all and everything may well have been squeaky clean and above board - perhaps the SI will answer those questions.
