20 Wishful Technologies That Will Never See the Light of Day (5 of 5)

Supersonic sound is illegal, no wonder supersonic jets are never happening

Yes, you heard it right. Any sound audacious enough to surpass the sound barrier is deemed illegal, according to the FAA regulation. It might be heart-breaking for you to realize that sufficing yourself with airplanes until your body is taken to the grave is the only option. Owning a supersonic jet is a fantasy to all, and shall always be.
Keeping mankind’s best interests at heart, it is better if it stays that way for eternity.
The idea of owning a jetpack shall always remain just an idea
You’ll probably never have your jetpack, thanks to its chances of belaboring the market being none. Jetpacks have huge structures and are always on their beta mode of functioning. It’s unpredictable where and when they might start to act erratically, henceforth the idea of ever letting it emerge as a unit of sale for the common man to buy is perceived as a blunder by every company. And if at all you find your life precious enough to ever lose it, so should be the case with you!
You’ll never be able to travel faster than light

The sprightly speed of sound amounts to 767 miles per hour and that of light counts to 186,000 miles per second. So no, only Flash could catch up to its speed!
The Michelson-Morley experiment dates back to April-July 1887, where they attempted to detect the presence of luminiferous aether, a postulated medium which was believed to throng space. It only proved that the need for any medium to support light’s travel is dispensable. It can perpetually travel through anything- air, water, or even vacuum. Catching up to its speed shall always be mankind’s eternal dream.
We have to be satisfied with airplanes and drop the idea of a flying car
The event of Henry Smolinski and Hal Blake being struck with the idea of putting their brains together to work out the invention of a flying car dates as early as the 1970s.
They coalesced a Cessna into a Ford Pinto, only to result in the detachment of the former and the men’s tragic death. Since then, never a one has attempted to even explore the conceptualization of such an invention. News of promising prospects of the same has always circulated the air now and then, but nothing has been engraved on stone as yet-and probably it will never be. The sublimest of scientists can join hands with the finest futurists and the chances of ordinary men risking their lives to test such an invention after such numerous failed experiments would still be 0. We’ll never get to experience what it is like to have such technologies exist in the real world, or it’s perks. But hey, we can surely fantasize about them, right?
After all, a few made-up scenarios on a nice day will never hurt our little heart!
