@ 14:11 UTC : Never seen them there, special indeed. But in line with the Specials' MO to land where they don't attract the attention of the untrained eye. If it landed at Sigonello it would have been obvious it's a military machine despite its plain look.
But you have to wonder : what's in Pantelleria for them ?

@ 14:50 UTC : Whatever they had to do in Pantelleria it got done real quick. They're off again.
