Brian,
How do you still manage in Nov 2009 (30 years later) to write as a Journalist that "Iran claims" as if to invalidate/dilute the iran point of view.
The "Iran Claim" as you write can be investigated for the enlightenment of your readers at the following web pages:
http://en.wikipedia.org/wiki/France%E2%80%93Iran_...
http://en.wikipedia.org/wiki/Eurodif
From the information gathered you can build up your own investigation and one day, may be you would understand why the iranians don't want to trust the French.
Regards
