Apparently planes went to that location and couldn't find any debris. ...and then another weird piece of the puzzle:

Adding to the mystery, The Wall Street Journal reported that U.S. investigators suspect the plane flew on for four hours once it lost contact with air traffic controllers, based on data from the plane’s engines that are automatically downloaded and transmitted to the ground as part of routine maintenance programs.
Maybe there's a chance this plane is sitting somewhere in India on a quiet (and long) runway? That plane needs a runway that's nearly a mile long to land...not much chance of hiding it (and certainly not for this long with all of those people and cell phones). Seriously, a west direction for four hours at 550mph is at least Sri Lanka. Looking at Google Earth, that plane could have reached the western side of India with that time / range.\
Too bad those engine signals don't include a latitude / longitude...this is just silly.
