Why did Roald Dahl plane crash in the desert?

Excuse me, but could you please clarify what you mean by "Roald Dahl plane crash in the desert"? Roald Dahl was a renowned author, best known for his children's books such as Charlie and the Chocolate Factory and The BFG. I'm not aware of any documented instance of him being involved in a plane crash, especially one in a desert. Could you possibly be referring to a different individual or perhaps a fictional scenario? If you have any further details or context, I'd be happy to try and provide a more accurate answer.
