Security Code Attempt
I have tried to follow-up on the last hours now and wonder whether there has been a source and/or confirmation that the captain did indeed try the security code (30 sec call sound in cockpit, easily to hear on CVR) and that this attempt was denied by the FO?
Earlier, I had read somebody state that LH CEO stated this. But from the TV material I saw now, one cannot derive that. Thanks for your help.
