One of the most intriguing aspects of this whole subject of who dunnit in the cockpit of MI 185 was a letter sent by a former Silk Air foreign captain to Silk Air management a few weeks before before the crash happened. It was later given to lawyers acting for the relatives of the dead passengers but was not offered as legal evidence of any blame. The foreign captain had been offered an extension to his employment contract. He thanked management for the offer of extension but declined stating that he never wanted to risk his life flying an aircraft after the deceased pilot was an operating crew member. He wrote that he was extremely critical of the way the deceased pilot conducted his flying with passengers saying the structural integrity of the aircraft was often compromised by the severe handling technique the deceased pilot was known to adopt while flying passengers. The captain who wrote that letter to Silk Air management was an experienced 737 contract captain from the Middle East. He voiced strong criticism of the system that allowed the deceased captain to carry on flying despite numerous evidence that he should have been grounded. For the Mods I hope this information does not cross Pprune editorial boundaries. If this is any possibility of this please remove the post.
