You can't police what you don't see and I quote from the preliminary report;
"A playback of a recording from military primary radar revealed that an aircraft with a
possibility of MH 370 had made an air-turn back onto a Westerly heading crossing
Peninsular Malaysia. The search area was then extended to the Straits of Malacca."
Despite various press reports and overwhelming conflicting information, the Malaysian government are not prepared to say that they actually saw MH370 on radar in real time. That report indicates that it was only after playing back the tapes that they took any kind of action based on radar information.
Mr 2hats on 4 corners was IMO disingenuous in answering a question with the rhetorical of asking should he have ordered it shot down. The answer he should have given was; you can't intercept what you can't see.
At this point in time I haven't seen a single reliable report of what was seen on radar and more importantly nothing released in any briefing. The altitudes perceived of between 12 & 45000 haven't been mentioned in the prelim report
and IMO the only reliable one is 5000ft based on the gap in the unidentified track which was shown to the Chinese press.
IMO the only radar data they had is that single 200nm NW track and that was discovered only after replaying tapes.
Embarassing for the Malaysian government to admit that a B777 can transit their airspace without being seen but in the interests of finding this plane it's time they specifically stated what they saw on radar.
