Intersting..I have not heard of this before..I have heard that many pilots call reporting "sightings" career killers. But have not heard about fines and imprisonment..Do you have any links to this by chance?

I think those refs are around the net. I don't recall where. Have seen them in books and on the net and don't keep track of such stuff.
I'd check first at the DISCLOSURE PROJECT site.
Or, talk to airline pilots. Some know and some seem not to or pretend not to.
