Claim:
1. An aircraft capable of a rotary wing flight mode and a fixed wing flight mode and capable of transitioning in-flight via a transition flight mode wherein the aircraft transitions in-flight between a one of said rotary wing flight mode and said fixed wing flight mode; said aircraft comprising: a thrust device for imparting thrust to said aircraft; a fuselage having a longitudinal axis which is perpendicular to a vertical axis of the aircraft; the fuselage having a lateral axis which is perpendicular to the longitudinal axis and the vertical axis; at least one helicopter main rotor operably mounted to the fuselage with its rotational axis mounted substantially aligned with the vertical axis of the aircraft; the at least one helicopter main rotor comprising rotor blades rotatable about its said rotational axis, and wherein the rotor blades can be stopped in-flight; the aircraft having at least one control device operable in said transition flight mode in-flight between a one of said rotary wing flight mode and said fixed wing flight mode; said control device orientating the aircraft to travel with a relative airflow to the entire aircraft, in-flight; said relative airflow substantially aligned with the rotational axis of the at least one helicopter main rotor and in an upward direction relative to the aircraft, the at least one control device also acting to stabilize and control said aircraft during the transition in-flight between a one of said rotary wing flight mode and said fixed wing flight mode.
