For what it's worth:
I met Gerald Howarth in 2000 when he came to have a look around the company I worked for "as a local MP keen to show his support for local business". As soon as someone mentioned that I used to be "on Chinooks" he ignored the bosses and spent half an hour quizzing me on my view of the Mull crash.
Mr Howarth would seem to be well versed in the case and I'm sure wouldn't sweep it under the table as other people may think.
