Analysis request: phone footage from Pennines, two weeks ago - anyone recognise this?

I've got about ninety seconds of mobile phone footage from a hike in the Pennines (near Hebden Bridge, West Yorkshire) from about 14th November. I filmed something that I couldn't identify at the time and still can't. Before I upload it here publicly, I'm asking for some preliminary analysis from people who've experience with identifying aircraft, drones, etc.

The object (or objects - there might be two) was stationary for about thirty seconds, then accelerated away at a speed that seemed... unusual. Not impossible for modern aircraft, but the acceleration pattern was weird. No visible propulsion, no sound (though wind noise on the recording makes audio analysis useless).

The footage is phone video quality so not brilliant, but it's the clearest thing I've ever recorded. I don't want to release it publicly and have YouTube conspiracy channels claiming it's definitely aliens, but I also genuinely don't know what I filmed.

Thoughts on whether I should post it here? And would an analysis be helpful or just speculative?

Absolutely post it. This forum has several people who do genuine analysis - not the 'ALIENS CONFIRMED' type, but actual people who think through possibilities. The Pennines area has had some interesting sightings historically so location-wise it's credible. The fact that you're cautious about wild speculation is a good sign - means you're looking for actual answers.

For analysis to be useful, include metadata if possible: exact location (GPS coordinates if you have them), exact time, weather conditions, atmospheric visibility, direction the object was moving. All of that helps people rule out prosaic explanations. And yeah, post it. Worst case scenario it gets identified as a helicopter or something. But if it's genuinely unusual, this community will treat it seriously.

The Hebden Bridge area is in a decent UAP hotspot actually - Yorkshire has had some interesting incidents. The acceleration you describe is worth documenting precisely. Modern military drones can move fast but they usually show visible propulsion or control surfaces. If you genuinely saw acceleration without visible means, that's interesting. Upload it and brace for both respectful analysis and complete nonsense in the replies.

One thing though - if the footage is from your phone, check if there's any metadata embedded (EXIF data). You can strip personal info but keep the timestamp and location data. That makes analysis way more credible. And honestly, if you can't identify it after posting here, you'll have done your due diligence. Sometimes the answer is just 'genuinely unidentified' and that's valid.
