He wasn't abandoned anywhere. We disqualified him from the Rally for a number of reasons and prepared everything for a safe return to Khartoum where he would have the support required to fix the discrepancies.
He ignored our advice and promptly got lost again (in ETH) and then had a forced landing in South Sudan (his third in 2 weeks).
We are providing as much support as is possible (working with the FCO) as far as Kenya where we hope he will arrive shortly.
As far as accepting him in the first place, we wanted to help him realise his dream of flying to Cape Town. A mistake, perhaps, but made with good intentions. Indeed, once he's got to Kenya the 'difficult' bit is complete - so he may still manage to achieve his dream.
