I think both the helicopters were from KIDL (but not 100% certain).
From what I hear, one of the passengers in the crashed aircraft was a Californian entrepreneur who had actually bought a stake in Lobolo Camp, on the western shore of Lake Turkana. All of the passengers in both helicopters were friends of his who he hoped would invest in a new adventure tourism project in Kenya. Now all those dreams will probably have perished because of disregard for the rules by people who ‘knew better’.
Irrespective of the actual cause of the crash, the fact still remains that flight in non-IFR helicopters with non-instrument rated crews is illegal in Kenya and in hostile terrain like that at night, the chance of surviving a major failure is minimal
