Cielos de Peru is the nom de plume of STAF.
They like to do long-term ACMI leases - and will paint their logo and colors on the aircraft. Gemini had an MD11 done up - actually a flashy looking plane. Made a fool of myself, first time I walked out on the ramp, looking for my plane, not knowing it had been painted!
They also run a few DC10's that they own. But I hear World was working for them again, so could be one of theirs....
