the ftl scheme works fine as long as it is adhered to.we all get tired for many reasons not to do with flying and many that do,like reporting for duty at 0500 or 2230 and working varying shift patterns.i find it difficult to rest before late starts and am always weary very early in the morning,but we are not machines.no different than lorry drivers,police officers,nurses,doctors ,the list goes on,all with varying responsibilities for peoples safety and their own.bit of a non story for me.
