Comments that are (a) really short and (b) not obviously substantive almost always get downvoted. If instead you had written: "Could this be an April Fool?", people would have probably have recognized it as a sincere question.

Please don't add comments about getting downvoted, though. As the guidelines say, it makes for boring reading.

This was published by NRK, the Norwegian equivalent of BBC on April 3rd, and the guys in the video seem sincere. I suppose it could convievably be an elaborate April fools prank by the skydivers if they talked to NRK on the 1st, I suppose. But I suppose they would have come clean by now.

Not April fools'. The story was published by NRK today, 3. of April.
