The bit where they get the detail wrong is: the VTOL generates a puff of air about the diameter of the wings, once. What it would actually need to generate is a huge blast on the order of a helicopter lifting off, continuously at least for the first few seconds. A single blast would leave it plummeting and it would need to pull some harsh gees to get up past stalling speed before it made a splat on the ground. Looking at the animation, maybe it was doing exactly that - but how did her arms not snap off?

Possible methodology:

- Explosive single VTOL blast.

- Plummeting with the jet throttled to max.

- Wing-in-ground effect lowers effective stall speed so acceleration can proceed skimming inches over the ground.

- Up to speed and lifting away from the ground to full flight.

It sounds crudely plausible, but terrifying and not something to do without mad skills.
