Because of pollution and the intriguing subject of climate change, planes are in the bad books of many governments from all around the world. It is indeed a very worrying thought to imagine a world without planes. If there is a need for a more environment friendly transport system, you can be sure that poor people will no longer be able to fly, as flight prices will have gone up. The only other mode of transport that is even comparable ( in speed and in capacity) to planes is trains, but how on earth will governments and railway companies get the money to lay down the train tracks ? Though general aviation wouldn’t be affected as much as commercial aviation in the case of new laws about air pollution, it isn’t as easy as you think to just buy a little turboprop and fly it around. First you either have to hire a pilot or get a licence to fly a plane ( which is pretty expensive all things considered [ a private pilot’s licence costing around $10’000] ) and then you have to pay for maintenance, fuel, an AOC ( Air Operator’s Certificate ) and much more ! If electric planes do take off, good, but currently lithium batteries are hardly successful. If you have any suggestions or ideas about what the future of planes might be, just comment underneath ! I will continue to write articles and thank you for reading this post ! 4th of March 2020.
