Apologies, my email in the videos is incorrect. It is drjohnd1974@gmail.com These are sightings taken mostly along the South Coast of England. The observations are compared to three possibe Earth models to determine which one/s can explain the observations. Take from these observations what you will and most importantly do your own research. I don't have any answers, but happy to discuss with anyone who is not intellectually dishonest and can accept not having answers and jumping to conclusions. Best John
About Dr John D.
Dr John D. publishes long-form videos on YouTube under the handle @drjohnd.9508, working from Great Britain. The channel has about 5,430 subscribers and roughly 147,000 lifetime views across 126 videos. Most videos document sightings taken along the English South Coast, which are then compared against several Earth models, and the presenter often invites viewers to draw their own conclusions.
Uploads have slowed sharply, with no new videos in the last 12 months, and the most recent wave dates to 2023. Viewers are likely a small, older, mostly British audience interested in alternative physics and observational methods; these are estimates, not measured data. No brand work is visible in the dossier.
At a rate of $20 to $35 per 1,000 median views, a sponsored video would cost roughly $150 to $250, which is a CPM of $20 to $35 compared with the $10 typical for paid ads. Brands with an optics or hobbyist angle may find this a fit, but the low view count and dormant schedule limit reach.
