Clearly not UPS packages. For one, all our packages that go on planes are loaded into "cans" that are pre-packed within the building. They aren't loaded via conveyor on the Tarmac.
Second, video is clearly being shot from within the plane. Seriously doubt any employee, union or management, would video this and put it on the Internet.
Perhaps someone who can identify planes via their the color or markings on their wings/engines can tell us if this is a model UPS uses. Something tells me no.
Thread gets 1 star for a half-hearted troll attempt, and "inceptive scribe prefers the company of gentlemen". Those of you familiar with Internet memes (as well as BC TOS) should enjoy that line.
