Yes rustle you can report what ever you like
Accident and Occurrence Reporting | Aircraft | Operations and Safety
Note the voluntary item.
http://www.caa.co.uk/docs/33/CAP382.PDF gives the whole thing.
It doesn't work the way a lot of people think it does. Its not a crimestoppers system or for that matter a beating stick for bullys and sorting out differences of opinion. Its a safety statistics collection scheme.
The only reply that you going to get out of me if threatened with "I am going to file a MOR on you" is crack on mate if you want the caa to know your clueless.
Just look at the hundreds of MOR's filed about pilots at Oban. To my knowledge not a single one has been spoken to or even asked to account for their side of things.
