Anyone know what this thing is? Some kind of flying hovercraft?

This submission doesn't contain an analyzable aviation news article. What's provided is a Reddit image post — a user question with a photo link — and no article text, research context, or identifiable subject matter. The linked image is hosted on Reddit's CDN and is not accessible or viewable here, and no research context was returned to fill that gap.

To write the kind of rigorous, fact-based analysis appropriate for professional pilots and aviation operators, there needs to be an actual article, identifiable aircraft or event, or substantive research context to work from. Fabricating an analysis around an unknown subject in an inaccessible image would not serve that standard.

If you can provide the actual article text, identify the aircraft or event in question, or supply usable research context, a full analysis can be written from that material.
