@RAT 5... See first quote. Pretty much everyone and their grandmothers was trying to be oh so helpful in relaying a frequency to Korean, to the point that 121,5 was blocked for extended periods. It started with someone offering Radar to attempt to relay, all well and good. But then people started chiming in on their own, relaying incorrect frequencies, stepping on each others transmissions and being generally useless...
And apparently none of them was listening for replies to their helpful transmissions as I heard Korean Air 917 transmit their intentions several times ("Korean Air 917, if anyone receives please respond. We are heading/landing Delta Kilo Bravo" where DKB is a VOR near Stuttgart I believe?).
I opted to relay that message to the frequency that they wanted Korean on, no idea if it was helpful but it seemed more sensible than falling over others trying to relay a frequency to an aircraft that quite obviously has radio issues and was not receiving. One friendly Speedbird was even so thoughtful to spell out the frequency one number per two seconds, therefore blocking 121,5 for about 15-20 seconds.
I'd hope everyone that was up in the air over Germany that night will take a bit of a look at their radio discipline... Maybe keep the frequency clear and don't get involved unless requested or offer your assistance before spamming 121,5.
