Reply to comment by ObituaryPegasus in Seattle-based Jetoptera is developing a vertical takeoff aircraft that can travel at almost 1,000 km/h with a radically simplified new type of engine. With almost no moving parts, it uses super-compressed air to create vortexes for thrust. by lughnasadh

The people who say this conveniently omit the myriad of valves and pumps and switches and mechanical computers (or computer computers) and bearings and fluids and reservoirs that are required to safely feed fuel to the engine, manage its airflow/temperature/RPM/acceleration/pressures, and lubricate it.

Also the hundreds or thousands of turbine and compressor blades
