Watching the BBC News at lunchtime, and the fearless reporter duly informed the world that, regarding aircraft safety, they can fly, land and.....take off.... on one engine.
True, if the aircraft has one engine that is. A minor detail I suppose.
And since when, or with which operator, has a duplicate inspection been required after routine oil replenishment?.
Back to the sensible comments.... and the pure speculation, always ans interesting combination after any incident.
