One of the comments at the site had an interesting theory that makes some sense. That the pilot was going to turn around and crash into the towers in Kuala Lumpur. Maybe out of protest for that politician he followed who just got sent to jail that afternoon. Maybe we or china shot the plane down when it didn’t respond. Still, I think there wouldn’t be a good reason to hide any of that.
If the pilot had intended to take out the Petronas Towers, or if there was a legitimate emergency at the time when the transponder quit, such as a fire, the proper action would have been a 180° turn.
In the case of an emergency, his goal would have been to land at Sultan Mahmud (TGG), which has an 11,417 foot asphalt runway perpendicular to the shore, a distance of only 111 miles. Obviously, he would have declared an emergency, and hopefully TGG would have been ready.
On the other hand, if he were bent on a suicide run, he more than likely would have made it to the towers before being shot down.
But what actually happened was, the transponder was turned off, there was no mayday, and the airplane headed west, not south.
How do you say LETS ROLL. In Malaysian?
