IT'S A HOAX! That is my opinion when I received and watched these pictures. I've receive this picture from an e-mail titled "Air Asia Crashed at KL Airport - News Not Covered By Media". To me this is just another prank. Yes the image are real and there were no superimpose inside, but the title is misleading.
I believe it was Air Asia conduct some safety training cum assessment on how effective and fast their emergency response are, thus 'memperbaiki' any standard emergency operating procedure flaw.
Look at the bottom of nose of the plane... no crash or 'remuk-remuk' right? If you watch Are Crash Inventigation on National Geographic Channel, you might learn something, especially when someone wants to 'tipu' you.
