THEORY: What if flight #MH370 partially collided with another object? #MalaysiaAirlines

I posit this theory as the news is conflicting as to where the one plane wound up, off the coast of Vietnam, as per the oil rig email, or, in the Malacca Strait, as the Malaysian military tracked an hour later.

What if there were TWO PLANES that partially collided, sending them both off course? That would explain how an oil rig employee would see a falling plane in the South China Sea, while the Malaysian military would be tracking another in the Malacca Strait at about the same time.

The trouble with this theory is that no one is reporting another plane missing, at least, not that we know of. We simply can't have two crash sites 1,000 miles apart. This is the only way to explain two sites.

If the 2nd plane is a military plane, it would explain why a 2nd plane isn't being reported.
