Bit harsh...
Some of them are very good and decent workers, including the one that unfortunately hit the EZY the other week.
Some aircraft are more loader resistant than others, the 146 appears to have been built with them in mind.....
They are made by Mallaghan, but I've only seen them at BHD before.
The IOM airport insists on left hand drive ones as well, which means Flybe can't use the rear steps. A pain and often the cause of being unable to make up delays.
