As a group Aviation does not exist at the moment, but if you are interested in old aircraft and similar I can redirect you to a person who organises superb trips to Aircraft Museums, etc.
Some organisations who organise trips are:
Bristol Aero Collection Trust
Rolls Royce Heritage Association
Royal Aeronautical Club
All of whom run very good lectures during the dark months of the year.
BACT are in the throws of producing the Bristol Aerospace Centre, which features Concord as the main exhibit.
The museum will open middle 2017 and the Trust will need more members to act as volunteers
If you would like more information on any of the above, please contact me Bob Milsom 01454 850033 or by email via the link!
