I think Vanity Unfair is a perfect pseudonym. No, of course these aircraft you list don’t perform virtually noiselessly with a hum at extremely slow speeds nor can any of them turn on their own axis as Steve Mccarron points out below and nor can humans withstand such massive positive or negative G-Forces with impossible turns other than on standard aircraft which is what all of these are. It’s so annoying when people post and don’t research other than give names of planes that simply can’t perform the way the flying triangles do, especially if you’ve never seen one and it’s obvious he/she hasn’t otherwise they wouldn’t have posted a list of aeroplanes.

Later in his Hilton Hotel suite, Quaid met with Rekall spokesman Dr. Edgemar (Roy Brocksmith), who observed that Quaid was in the middle of his dream vacation: "You're not here and neither am I."

He forecast the remainder of the film (and Quaid's experiences) with his statements, when Quaid threatened to kill him:
