They seem to have had a patch of bad luck back in 1991 when a 707 they were selling to the US military crashed after a wingstrike on take-off from an Arizona boneyard killing two. When the NTSB arrived they discovered the Irish mechanics servicing the plane had fled, despite being witnesses to the crash. They also discovered that the aircraft's temporary operating certificate had been granted by an FAA recognised DAR who wasn't qualified to certify large aircraft, the wheels were'nt capable of retraction, there were only 4 working instruments left in the cockpit (out of more than 50). Among the ones ripped and sold for spares was the main turn and bank indicator which doesn't appear to have helped when the pilots (mostly unqualified) took off with a misset rudder and failed to spot their angle of bank.
Another spot of bad luck a few years later when the Brits grounded three of their 707s at Manston because they were unhappy with their Third World flag of convenience registration.
The boys also seem to have done business with a number of airlines operating out of Ostend, especially Liberia World Airways. Interesting place, Ostend.
