I'm not too sure about Orient Thai. There are several other current/future B767 operators in Thailand.
Sunny airways
R airlines (Future)
Business Air
Asia Atlantic airlines
Nevertheless,Some interesting bits on wiki w.r.t. Orient Thai
On September 2004, an Orient Thai 747 flew within 200 meters of Japan's Tokyo Tower over the heart of downtown Tokyo.
On July 22, 2008, shortly after the crash in Phuket which killed 89 people, and after the internet publication of illegally excessive work hours and check fraud Orient Thai and its subsidiaries were ordered to suspend service for 56 days due to failure to train, failure to have a safety program and failure to supervise safe flight, check ride fraud and breaking the law at Orient Thai and One-Two-GO.
Here is a link to the damning report on Orient Thai and it's now defunct subsidary One Two Go airlines
