G-DRFC did fly for Euromanx on a fairly regular basis during the period when they were expanding too quickly, but had hardly any aircraft or crew of their own. I recall that it had a strange colour scheme at that time, with palm trees on the tail.
G-IONA was used by Euromanx to launch their LCY-IOM route (in 2005?)when they took over from BE and the promised RJ-70's hadn't arrived. It was around for several months.
