A strange footage of a metallic sphere hurtling through the sky, plunging into the ocean, re-emerging and then splitting into two was recently retrieved.

The video clip  had been shot in Aguadillia, Puerto Rico, on April 25, 2013, but the video footage was released only recently by a Department of Homeland Security (DHS) whistleblower, says The Scientific Coalition for Ufology (SCU).

It was an object that was "monitored" by people in an aircraft from the US Customs and Border Protection.

"Assuming the video isn't a clever hoax - which is always a possibility these days - it's a fascinating piece of footage," commented Nick Pope, a UFO expert.

"About the only conventional explanation that might fit the bill is that this is some new drone, but the entry and exit from the sea and the apparent splitting in two of the object makes even this explanation seem unlikely."

It was first observed by the crew of an aircraft that saw the strange, pinkish, red light above the seas. As they had not been told about incoming traffic, they just radioed it in. The tower too had seen it, they learnt.

Amazingly, the three-to-five-foot object raced at a speed of 40mph to 120mph. It then vanished into the ocean for half a mile, then resurfaced and got divided.

A spokesman for SCU said: "There is no explanation for an object of traveling under water at over 90mph with minimal impact as it enters the water, through the air at 120mph at low altitude through a residential area without navigational lights and finally to be capable of splitting into two separate objects."

SCU said they wanted to confirm the authenticity of the video before it could be released. The project also has six scientists investigating it.
