<<it was maybe a bit extream to call mayday dont you think>>
So you don't think executing an emergency descent, without ATC clearance, in some of busiest airspace in the world, warrants "immediate assistance" from ATC in ensuring the area below you is clear?
Or maybe you do not know what "Mayday" means? Especially judging by this comment <<However can you ever be to over protectuve of your aircraft>>
Might I suggest it was up to the crew to judge whether or not a Mayday was warranted, and not someone wo by their own admission knows nothing about what happened....
