By Alberto Riva - According to a local newspaper, residents of a remote island in the Maldives, Kuda Huvadhoo, spotted a plane a 6:15am local time on March 8 that could have been the missing Malaysia Airlines 370. Eyewitnesses cited by the paper said they saw "a jumbo jet," white with red stripes across it, flying low and very loudly. The description of a big airplane in those colors is compatible with the Malaysian Boeing 777.

The islanders said they did not recall seeing any airplane there, and at that height, before, making it unlikely that what they had seen was a normal takeoff or landing by another passenger jet.   

The time of the sighting also matches what we can deduct about the plane's range and its known whereabouts.

6:15 am in the Maldives is 9:15am in Malaysia, so the sighting would have occurred seven hours and 45 minutes after the last radio contact, the now-famous "All right, goodnight" at 1:30am Malaysian time over the Gulf of Thailand.  

A 777 series 200ER, with a nearly-full load of 227 passengers and 12 crew, cargo, and fuel for the scheduled five and a half hour trip from Kuala Lumpur to Beijing plus reserves, would typically be able to stay in the air for a maximum of about eight hours. That makes the presence of the aircraft at six in the morning local time in the middle of the northern Indian Ocean technically possible.  

In fact, the distance between the point of last radio contact and Kuda Huvadhoo is 2,000 miles, which a 777 at cruise speed would cover in far less time. Flying in a straight line from the Gulf of Thailand, MH370 would have appeared over the island no later than 3am local time, well before sunrise.

But the plane may not have flown in a straight line, for whatever reason: possibly a hijacking, and maybe the crew's attempt to foil it. Or it may have flown at very low level to avoid detection, where the air is thicker and jet planes fly slower because of added drag. It may also have been flying at reduced speed to conserve fuel, either because whoever controlled the plane wanted to maximize its range, or because jet engines are less efficient at low altitude and consume more than at height.
