The photo of the jagged passenger-sized hole blown in the side of a jet shortly after it took off from Mogadishu in Somalia last Tuesday is the stuff of air traveller nightmares.

Immediately to the left of the rupture, some images show a smear of blood from the suspected bomber, who was the only fatality in the botched attack, as the Daallo Airlines A321, which had reached an altitude of around 14,000 feet, immediately returned in one piece to the Somali capital’s airport.
