Electric vehicles that can take off and land vertically, but then fly like a plane, are already being sold and used by hospitals and shipping companies. These vehicles have 5 batteries that give it a range of over 350 miles using current battery technology, though the batteries are intended to be swapped over the life of the aircraft, much like the engine of a traditional aircraft, however, future batteries could feature improvements, meaning the vehicle gets better over time. The redundancy that Electric motors allow more easily than mechanical motors means this aircraft is far safer than anything else in the air.
Flying a VTOL aircraft seems out of reach for me as most are either helicopters or military, but an EVTOL seems like something that could be in reach for me within my lifetime.
Yeah the guy was saying the learning curve is very approachable for those with the right qualifications.
