[aiming at pilotless flying taxis Boeing wholly acquired flying car developer Wisk] Boeing acquired Wisk Aero, the developer of eVTOL (Electric Vertical take-off and Landing vehicle), wholly owned by Boeing. It is reported that eVTOL, also known as flying car, is an innovative means of air transportation, and it is also regarded as a solution to optimize the traffic pain points of the integrated development of urban agglomeration in the future. At present, as a civil manned aircraft used for regular passenger commercial operation in low-altitude environment, eVTOL is facing challenges in terms of safety and airworthiness certification.
