technology for aviation and stuff like that?

It was some kind of anti-gravity device, not a hovercraft

I saw the episode. Most of their tests were based on the magnetic force and one on convection (moving air currents). Nothing on anti-gravity. Further, to date there has been no observed anti-gravity. One theory, dark-energy, is far from definitive.

Like Silverbirch, I did not see the program, but it really depends on what technology used to levitate the device. A hovercraft that hovers above water uses massive amount of air pushing against the water to levitate itself. HIgh-speed magnetic train use magnetic lift generated by the electricity on the tracks to stay afloat.
The transportation device Silverbirch mention, depend the size, I suspect it does not really hover at all but has very precisely machines balls, used as wheels while the rest of the device platform "hovers" over the ground.
Also, the old sci-fi of hovercraft that people can travel through air is current pure fantancies since it was based upon the belief of graviton existance. However, after sub-dividing sub-atomic particles, gravitons was never found. The dream of anti-gravitity technology in Star Trek might never be realized.

Because it wasn't an actual "anti-gravity" device. it just resonated the air particles around an object and made it appear to levitate.
They proved that on the show by placing it in a vacuum. The object never moved.
It was just way to impractical.

I didn't see the programme, so I don't know what it was, but a lot of factories now use mini hoverpads to move things around. I've seen two men shifting a 20 ton radar.

it is still under the development stage it will happen soon

just because we don't see it's used publicly doesn't mean they are not using it
