A flight simulator business has fired an instructor who has figured prominently in CNN's coverage of missing Malaysia Airlines Flight 370, saying he failed to turnj up for work on time and refused to dress professionally.

uFly company owner Claudio Teixeira said he fired Mitchell Casado in part for "shaming Canadians" by "dressing like he was 15 years old". Mr Casado's relaxed style of jeans and plaid shirts attracted wide attention during CNN's constant coverage.

Mr Teixeira said Mr Casado refused to wear a pilot uniform and made Canadians "look very bad all over the world". He said he received many complaints. CNN's Martin Savidge and Mr Casado logged many hours reporting from the fake cockpit at the company's office near Toronto airport, which has a simulator that is the same model as the lost plane.
