Unsurprisingly something here smells very fishy. Not the crew or their actions as that just seems, at first sight, to be a bad landing after disorientation in brownout as the result of a flawed landing technique. It might not be, but they wouldn’t be the first crew to have experienced this and I doubt they’ll be the last. But as soon as the name Caverton comes up and we suddenly hear about failures of CVR and FDR just before a very messed up landing my BS meter peaks up in the red. Do Caverton have any other flight data monitoring systems on their aircraft or is that only on the Shell contract 139s?
Villages in Nigeria don’t have the facility for drug and alcohol testing but if they were taken to a hospital for a check, they should and they were probably moved to Abuja or Lagos soon after so it should have been done there.
