Electric engine aircraft can be a very big advantage to aviation. 

Electric aircraft are silent, and they can be used for carrying people around cities. The small-size piloted- or drone aircraft can use also for carrying cargo. But the electric engined VTOL (Vertical Take-Off and Landing) aircraft, which are made by using STEALTH-technology are difficult to locate. And that technology allows the use of those systems for military purposes. 

The lightweight VTOL STEALTH aircraft can be equipped with electronic warfare systems, which allows them to jam and disturb the drones and enemy communication in a certain area. They can also be equipped with precise guided anti-tank missiles and also the systems can use things like laser microphones, lidars, and other types of sensors to control the area. 

Electric engines are making the aircraft silent, and they can hybridize to the hydrogen turbojets and super-and hypersonic aircraft. The electric engines allow that the aircraft can fly silently over the city area, and if the aircraft uses electric engines, it needs only electricity for operating. But the thing is that the in the same aircraft can install the electrolysis system, which separates hydrogen and oxygen from the water. 

In that case, the aircraft can fill the tanks by using liquid oxygen and hydrogen by using internal electrolysis and cooling systems. That allows making the new type of space shuttles, which are operating from the regular airfields. Those space shuttles would rise to a high atmosphere by using electric engines, and then they can start the rocket booster. 

There are two possibilities to make that thing true. The shuttle itself can equip with the origami-wings that can fold in. Or the small shuttle can take to the high atmosphere by using the auxiliary aircraft or mothership, which can take the shuttle to extremely high altitude, and then the small shuttle will shot to space. And the electric engines allow that the long wing aircraft can rise to extremely high altitude, and in the year 2003 the electric aircraft can reach easily almost 30 kilometres altitude. 

The traditional electric engines or blowers can install also to hypersonic or supersonic aircraft. Those blowers can offer the possibility of silent lift-off and landing, and when the aircraft is far enough from the cities, they can start to use regular turbines. And if those systems are using hydrogen, their operational range would be very long. 

For making hydrogen in the electrolysis chamber the system requires only electricity, and the electricity can make by using solar panels, or it can take from the ground by using the mothership plane. The mothership plane can rise by using electric engines easily to an altitude of 30 kilometres, and there it can drop the small-size shuttle for orbital and suborbital operations. 

The super- or hypersonic aircraft can use electric engines for silent lifting-off. The aircraft can travel to a safe distance from buildings before starting the turbines. And then the acceleration to the hypersonic flight can be made by changing the engines in series from turbines to ramjet and scramjet systems. If the turbines are included in the engine set, that allows the aircraft to operate also with low speed. So the lift-off and landing of that aircraft could be silent, but regular cruise might be used by using hydrogen turbines and other engines.
