Please forgive me for writing in English na kha (My hubby seizes my computer to play his game kha)
He saw this clip several times and doesn't believe the claim. He thinks it probably be the speed of the plane that makes the water from the ocean condensed kha...
This is the real thing krub. Very common phenomena called the sonic boom . It happens when an aircraft try to accelerate over the speed of sound . The sound wave emitted from the jet will reinforce with each other and "condense" just like in the video clip.
