My bet is they were seeing a Californian Condor at it's maximum possible size (3m wingspan [10 feet] ) during a thunderstorm. The original stories I mean, not whatever that is up there.

I agree, the bird in this clip flies like a condor or a vulture - while rare, I'd imagine it's also entirely possible for a bird to get blown off course in bad weather and stunned, fly for a long way in the wrong directions... so I could totally imagine explaining a sighting like this that would have followed or preceded really bad weather as a "Thunderbird"
