Wrong place - wrong time - and....
Debonair did not only operate 146's but was also hiring, at high costs, some F50's and F100's from wetlease-companies like Denim Air and EAE.
When you want to make a succes out of a low-cost-carrier never-ever hire high-priced turboprops instead of operating your own lost-cost-jet-fleet like the 146's (yes indeed, the 146's are very capable to operate on shorthaul routes at a minimum price!)
