Thanks Nekitamo!
This shows roughly a 15° inclination over equator, if we assume the tail/ring is in line with drone trajectory
(that seems to be the case with Chad's drone but not with Raj's one!)
A simple suggestion...
(I'm too busy now for more)
We have dates and locations for Yosemite, Tahoe, Chad, Raj, Brent etc. and a system to determine orientation trajectory (or the field orientation used, like for sail), with ring/tail oriented drone system, perhaps Roy's Dutton theory is applicable there?...
In 1997, Roy Dutton, a NASA orbit calculation specialist, has 'shown' that UFO sightings which seemed not to be correlated, were in fact correlated by a mother ship orbit.
To 'deliver' and 'retrieve' a probe, the mother ship must use a 'super orbit' to come near earth, these orbits make a special angle with equator (101 'markers' identified on equator) and thus sightings are 'spots' on 'lines' defined by orbit/date/location.
(Roy Dutton seemed to be able to make some previsions...)
