GPS, VOR, ADF etc would have prevented him just blindly allowing the autopilot to fly the ILS. From what I can gather, it was the autopilot that had the glitch trying to intercept the ILS. Any Capt or first officer with even an ounce of professionalism would be monitoring his progress down the tube (unless youre working for Ryanair/Eirjet ).
Its a bit of a non story really but its been reported on because the AAIB had to investigate it.
I'll bet John Stewart of Hecan Clearskies would be pished off if he came off his lentle eating holiday with his sweaty pie eating wife and was forced to catch the train from Humberside airport back home. He's probably one of those knobheads who buys his house dirt cheap because its next to an airport then spends the rest of his pointless life complaining about the noise. Send the fecker back to the stone age. Chod.
