[ATC]: Copy

…Short after, the F16 pilot gives the coordinates to the ATC…


Oh I remember watching the air crash investigation Episode on this.
Kinda forgot it a little bit
May need to rewatch it


Each time I see this video, I remember the moment when I heard with my mum in the news that everyone was dead, no exceptions…

I remember this crash clearly, as I also was scheduled to fly out of Athens a few days later. It was a scary feeling…


If you think this post is not needed, just scroll down…You come here after reading this terrible incident and posting this?

My opinion on it is that my uncle and cousin died there… I am sure this is better detailed than Wikipedia. If you don’t like it, just don’t reply, if you don’t have anything to say about it.

Besides that you could have PM me and discuss it there, instead of posting here


I remember watching the Air Crash Investigation episode on that.

cough cough
What’s my birthday?
Well, it’s August 14th.

Happy birthday!


I saw this on National Geographic’s mayday like 5 years ago. I was and still is amzed by that male flight attendant.


Really sorry for you loss mate, that must’ve been horrifying when you heard the news.

Thanks for the very informative post - I definitely learned something. What a horrific turn of events. RIP.


After some days we learned this in the news. Its been some years from when it happened, but still, it seems like yesterday…

Anyway…thanks for your kind words buddy!! Its really sad not only for me, but for anyone who lost a part of his family there…


Clearly people here took it the wrong way. I only said it Bc I felt like this was gonna be a trend like the “managing airports” threads. I’m sorry for your loss in the crash but it would be nice for people to indicate that they lost someone instead of just posting about the crash. It would bring more value and significance to the forum.

I am not posting to indicate that I lost a part of my family. I could have done it, if I wanted too…

Just a suggestion for the next time: As I have said previously, better PM the OP, instead of posting your off topic opinion here. Everyone here has a different story, which you don’t know… That’s why we have the Message option. You might want to see Mags advice about the whole thing:

Before we start getting off topic here, I would suggest you @N1RG and @Asdew take it in a PM.


Oh, I understood that incorrectly. Yeah, that’s not what I like.

I’m so sorry to hear that. I send my condolences. Must’ve been a hard time for you to hear this. But I’m sure your loved ones would’ve wanted you to celebrate them and not be depressed. Overall, this is a tragic accident. May all of their souls rest in piece.


Please keep the chatter in a PM please. Half of these posts should have been via a PM instead of the public thread.
