A toy launch apparatus, comprising: a projectile retaining element on the toy launch apparatus; a launching structure forward of the projectile retaining element, the launching structure comprising: an energy generating mechanism; and motor driven flywheels (46, 48) for propelling a projectile; a projectile barrel assembly extending rearward the projectile retaining element, the projectile barrel assembly comprising a step structure having a projectile receiving opening; an improvised projectile checking housing assembly of the projectile barrel assembly, comprising an improvised projectile checking housing comprising a first and a second sidewall (22A, 22B) each having a catch latch aperture (23A, 23B) rearward from the projectile receiving opening; a trigger assembly configured to move the improvised projectile checking housing towards the projectile receiving opening, and thereby to move a projectile from the projectile retaining element into the launching structure; an elongated structure in the improvised projectile checking housing, the elongated structure having proximal and distal ends thereof and a catch latch recess therebetween, and an improvised projectile checking spring mounted to the distal end of the elongated structure; an improvised projectile button positioned at the proximal end of the elongated structure; and the toy launch apparatus further comprising a locking key positioned intermediate the proximal and distal ends of the elongated structure and opposite the first and second catch latch apertures (23A, 23B), and a lock spring that downwardly biases the locking key; wherein the elongated structure is movable between a checking position where the improvised projectile button is pushed into the improvised projectile checking housing to misalign the catch latch recess with the catch latch apertures (23A, 23B), thus maintaining the elongated structure to completely close the catch latch apertures (23A, 23B) so the locking key may ride over the improvised projectile checking housing without dropping into the catch latch recess of the elongated structure, and a non-checking position where there is nothing to push against the improvised projectile button in a rearward direction against force of the improvised projectile checking spring, such that the first and second catch latch apertures (23A, 23B) expose the catch latch recess permitting engagement of the locking key in the catch latch recess so that the locking key locks the trigger assembly thus preventing further operation of the toy launch apparatus. a projectile retaining element on the toy launch apparatus;
