Is it me, or did you misread the 1st posting by Dagger Dirk
The hijacker ordered the pilot to fly to France, but the crew told him there was not enough fuel. And Morocco denied a request to land in the city of Djala in the Moroccan-controlled Western Sahara, so the pilot headed for Las Palmas in Gran Canaria, the original destination.
Sorry I cant see any intermediate landing here - the mess was created at the airport of departure - but he only manifested himself after take-off according to DIRK's posting ?
