1. An airlifting air tube apparatus comprising:
one or more propellers connected to one or more propeller motors, all of which are encapsulated by an exterior shell of the airlifting air tube apparatus, wherein the one or more propeller motors are configured to rotate the one or more propellers;
a flight control circuitry configured to control rotational speeds and rotating orientations of the one or more propellers;
an air intake path physically defined by an air intake opening on the exterior shell and an internal air passage leading to the one or more propellers encapsulated inside the airlifting air tube apparatus;
three or more outtake air tubes located on a bottom surface of the airlifting air tube apparatus, wherein the three or more outtake air tubes expel air drawn in and agitated by the one or more propellers and provide a sufficient lift force to enable the airlifting air tube apparatus to operate as a controlled flying device, and wherein adjusting a magnitude of expelled air in each of the three or more outtake air tubes triggers a change in direction or altitude during flight; and
an airflow control dish-based steering unit comprising an airflow control dish and a dish-guiding rail embedded in each outtake air tube, wherein the airflow control dish is configured to move along an axis of movement guided by the dish-guiding rail embedded in each outtake air tube to reduce or increase the magnitude of expelled air in each of the three or more outtake air tubes, which in turn provides a controlled steering of the airlifting air tube apparatus.
