I know it is fashionable on this forum to rubbish David Learmount and anything he says, but I have to say I pretty well agree with what he is saying about this. Everything points to a huge cock-up on the part of the RMAF radar, which their authorities have been covering up because of this inevitable "face" thing. If I were a Malaysian taxpayer I'd be asking what the heck is the use of operating highly expensive Su 30s, Mig 29s and F18s if unidentified aircraft can fly unchallenged across the country's airspace?
