THEORIES, SOME OF WHICH ARE 
IMPLAUSIBLE, AND SOME JUST 
DOWNRIGHT UNBELIEVABLE. 
>> Reporter: CONSPIRACY 
THEORISTS HAVE A BUNDLE OF 
THEORIES, ONE, THAT ALIENS STOLE
THE PEOPLE ON FLIGHT 370. 
>> OR THE TERRIBLE THING THAT IS
HAPPENING IS ATTRIBUTABLE TO 
ALIENS IS IMPOSSIBLE. 
>> Reporter: HE SAYS PEOPLE ARE 
DRAWN TO MYSTERY AND SUSPICION.
ESPECIALLY WHEN FEELINGS OF 
FEAR, ANGER, AND GRIEF ARE 
INVOLVED.
AS IS THE CASE WITH THE 
MALAYSIAN AIRLINER.
ON SOCIAL MEDIA, CONSPIRACY 
THEORIES ABOUT THE MISSING PLANE
ARE STILL GOING VIRAL.
THIS TWEET PRETTY MUCH COVERS IT
FROM TIME TRAVEL TO AN INVISIBLE
CLOAK FOR THE AIRPLANE.
OTHERS WONDER WAS THE PLANE 
HIJACKED TO AFGHANISTAN?
OR DID IT LAND ON THE U.S. 
MILITARY BASE KNOWN AS DIEGO 
GARCIA?
THE ISLAND IN THE INDIAN OCEAN 
HAS RESTRICTED SECURITY 
CLEARANCE.
BUT THAT HAS ONLY AMPED UP 
CONSPIRACY THEORISTS, SO MUCH SO
THAT IT FOUND ITS WAY INTO THE 
WHITE HOUSE BRIEFING ROOM. 
>> SOME REPORTS SAY THAT THE 
FLIGHT COULD HAVE LANDED IN THE 
U.S. MILITARY BASE, DIEGO 
GARCIA, IN THE CENTER OF THE 
INDIAN OCEAN?
DO YOU RULE THAT IN OR OUT?
>> I'LL RULE THAT ONE OUT. 
>> Reporter: ANOTHER CONSPIRACY,
AN OUTRAGEOUS INSURANCE SCAM.
THE MALAYSIAN POLICE CHIEF GAVE 
THAT THEORY LEGS.
LISTEN. 
>> SHOULDN'T IT BE SOMEBODY 
THERE ON THE FLIGHT THAT -- WHO 
BOUGHT HUGE SUMS OF INSURANCE 
WHO WANTS THE FAMILY TO GAIN 
FROM IT?
OR SOMEBODY WHO HAS SO MUCH 
MONEY -- 
>> IF NOT THAT, THEN PERHAPS 
SOME SUGGEST NORTH KOREA TOOK 
THE AIRPLANE. 
>> THE NOTION THAT NORTH KOREA 
WOULD CHOOSE TO EXERCISE SUCH 
AUTHORITY AND CAPACITIES AS IT 
HAS TO HIJACK THIS PLANE, THAT 
SEEMS IN THE REALM OF DESPERATE 
SPECULATION, TOO. 
>> OF COURSE NOT ALL THEORIES 
ARE AS IMPLAUSIBLE AS SOME OF 
THOSE.
OTHERS ARE MORE BELIEVABLE, 
PILOT SUICIDE HAS NOT BEEN RULED
OUT AS WELL AS RAPID 
DECOMPRESSION, WITH THE PLANE 
RUNNING OUT OF FUEL.
ANOTHER REASONABLE THEORY?
FIRE FROM LITHIUM BATTERIES THAT
BROUGHT THE PLANE DON'T OR A 
REAL CARGO PROBLEM THAT CAUSED 
THE PLANE TO CRASH INTO THE SEA.
>> OTHERS THAT HAVE HAPPENED IN 
HISTORY ARE PROBABLY A GOOD 
START, AND TO HAVE TECHNICAL 
EXPLANATIONS, THAT IS A LITTLE 
MORE SOLID. 
>> Reporter: MORE SOLID, BUT 
STILL NO CONCRETE EXPLANATION
