Gasman, as a fellow professional you will understand that certain information is not best handled outside of the arenas for which it was originally meant. Also most such information is commercially secret for obvious reasons. You will also understand that in the latest political climate it would be extremely wreckless and foolhardy for qualified engineers to furnish you with any aeronautical information, especially via this method of communication. After all we have no way of verifying your credentials and therefore it is justifiably prudent to deny any such a request in the interests of security. You may find greater success if you contact the CAA and explain your interests. If indeed you are genuine, then this may be the best method provided you can verify your status.
