A cradle 8 is suspended by two pairs of cables attached to a girder connecting two towers and is provided with a carrying loop 12, Fig. 4. up to which the aeroplane is raised by a hoist 45 and to which it is secured by a hook 3C. The cradle is swung into the launching position by the cable and winch device shown in Fig. 2, to which it is connected by a hook 14, Fig. 4, adapted to be released by pulling a rope 20 which frees a keeper 17. The aeroplane is released from the cradle at the bottom of the swing either by the pilot pulling a rope 38 or automatically by the tensioning of a rope 39, secured to a cleat 41, which after effecting the release of the aeroplane is freed therefrom by the parting of a belleerd coupling 44.
