Unless this footage is an elaborate hoax, it is powerful evidence shot in broad daylight. Air Force fighters give chase, buzzing a UFO craft (vimana) hovering, which then plunges straight down into the ocean. It ends with a black military helicopter ordering the fishing boat caught in the middle of the event out of the area.
The captain keeps yelling, "What's happening here?!" He then orders the person holding the camcorder to "turn off the machine," apparently as not to upset the helicopter which could easily open fire on them if it became aware that it was being filmed.
The bottom of the screen is the helicopter's announcement in Spanish. It translates as: "Abandon this zone immediately and direct yourselves back to port. There you will receive further instructions."
