Nothing dodgy about Skyblue Aviation. They are independent of Atlantic and train flight crew on the ATR42/72. As mentioned they are based in EXT.
Atlantic Express want to re-introduce an ATR42 for ACMI (Aircraft, Crew, Maintenance & Insurance) charters. The aircraft will be operated on their behalf by Skyblue. In this type of operation the flying can be infrequent (but there are no other UK-based ACMI operators using turboprops, so they might be onto something) but is usually not routine. One of my ex-colleagues (from cabin crew days) who used to do ACMI charters on Air Atlantique's ATRs loved it.
