On the Discovery channel:
The aircraft of the U.S. Air Force carried into the test zone a hydrogen bomb with a capacity of one and a half megatons. There was an accident and the plane began to fall. The pilots decided to drop the bomb - they dropped it and waited for an explosion.
It happened on the coast of one of the states at 5-30 in the morning.
The bomb fell into the sea in the mouth of the river and went into dirt to a great depth. No one can find her yet, and the authorities now deny the fact of the fall of this bomb.
Comments of the bomb searchers:
"This is a very dense area, and the explosion of the bomb at such an early hour could have shocked the locals!

Type of A-A! The pipet. Half-Megaton explosion could awaken peacefully sleeping Americans!
Fuck they woke up! :D
