For what it`s worth.
10 minutes ago ,i talked to one of my clients ,who stays every year in Malaysia from De. til March-
He told me public opinium there is,that the pilot has stronger ties to radical/anarchistic circles than the authorities have told us.
I'm currently in Malaysia. I have heard all of the speculation from the locals from day 1. The captain/co-pilot having stronger ties to radical/anarchistic circles is a new one to me.
Several of my friends and neighbours are working for MAS, Firefly and Air Asia. I spoke to a colleague of Captain Zaharie on the Sunday after the flight had been declared lost. He had nothing but praise for the guy, he believed the Captain to be one of the best pilots within the company and he himself had been a student of Captain Zaharie. He continued to say that if anyone could recover an aircraft from an almost impossible situation it would be Zaharie.
I'm not ruling out anything but suicide and hijacking are way down my list!
