Dear Bealzebub
Thank you for your post. Yes, I am a rookie compared to you guys, as you already know. I just wanted to know the reason for which flight crews would fail to land an aircraft at 0-visibility and you have summed it up well and so did lizbet, FlyingforFun and the rest.
There is so much to explore and to learn in this fascinating world of aviation! sorry if I have kicked you guys with silly questions, but as I said, I was curious and now that you have answered my question, I am thankful to you all.
Richie
