1. A flight device which has at least one propelling unit for flying in the air and which is throwable by a user, said flight device comprising:

  • a controller that drives the propelling unit after throwing is performed by the user, such that the flight device flies based on a state of the flight device at a moment when the throwing is performed;

    a flight sensor that detects acceleration values; and

    a touch detection sensor that detects a touch of the flight device by the user and a release of the flight device by the user;

    wherein the controller calculates velocities of directions of individual coordinate axes of a predetermined absolute coordinate system at a moment after the throwing is performed, and calculates an initial velocity, a horizontal angle of the throwing on a coordinate plane parallel to the ground, and a vertical angle of the throwing on a coordinate plane perpendicular to the ground, based on the velocities of the directions of the individual coordinate axes; and

    wherein the controller calculates the velocities of the directions of the individual coordinate axes at the moment when the throwing is performed, by integrating an acceleration value of the direction of each of coordinate axes output from the flight sensor, from a time when the acceleration value of the direction of the corresponding coordinate axis exceeds a predetermined threshold, to a time when the touch detection sensor detects that the flight device is released by the user based on the acceleration value of the direction of the corresponding coordinate axis.
