Former UFO chief Dr. Sean Kirkpatrick has offered up a possible explanation for some military UAP sightings.
Dr. Kirkpatrick, who previously headed up the All-domain Anomaly Resolution Office at the United States Department of Defense, has suggested that mysterious spherical objects sighted over US military bases along the East Coast could be high-tech Chinese drones.
Witness testimonies have often described these objects as perfectly spherical and silver or metallic in appearance with no discernible means of propulsion.
Interestingly, the idea of a drone resembling a metallic sphere is not that far-fetched.
Pictures posted online (see above left), for instance, show a drone prototype developed by academics in Singapore in 2022 that seems to match the UAP descriptions almost perfectly.
Footage by Swiss-based drone maker Flyability (see video below and image top right above) also demonstrates a similar design, with the drone's mechanisms contained within a spherical gimbal.
The idea behind the design is to provide a buffer of sorts to help the drone avoid damage during collisions with physical objects.
When the entire thing is contained within a spherical external shell, it would appear - for all intents and purposes - like an anomalous, featureless sphere floating eerily around.
Whether or not drones like these explain any of the UAP sightings, however, remains a matter of debate.
