Dunno about Luanda, but my partner tells me that one of our kilo4 mechanics nicked a prop off one of our CL44s in FIH and sold it as scrap. To make matters worse, it had the best times remaining and he'd been planning to flog it to FIA for their Guppy for $85,000!
We've also had tools, a satphone, cash, CDs, boom-box and various other nick-nacks go missing. On top of that, we've had thousands of dollars worth of Jet A1 get drained off. Sometimes I think that if it wasn't so heavy, those b'stards would nick the aircraft as well!
Ah well, you know what they say - if you can't take a joke, don't come to Africa!
