Yr right:
Another illiterate, illogical, simplistic and incorrect posting!
A dc8 or 707 took off out of South America. After the aircraft was washed they failed to remove the tape over the static system. After take off they noticed the problem. Instead of staying in slight of the lights of the city they went off into the dark. Lost all visual reference and ended up in the sea with a total loss of life.
Key word here. VISUAL.
It's a pity you don't know what you're talking about, and have selected an example where crew competence (should I say incompetence?) was the issue. How about the Cathay B744 that flew from Xiamin to Hong Kong, IMC (I repeat in IMC, as they had no choice)? You haven't heard of this? Probably because they landed at their destination with a minimum of fuss - unlike your example, they were a competent crew who simply aviated/navigated/communicated.
Your assertion that the key word here is VISUAL is bollocks.
