An aerial delivery platform comprises first and second modules (10a, 10b) each having a respective load-bearing surface (14). The modules (10a, 10b) are hinged together for relative flexing movement about an axis (24) between the modules (10a, 10b). A superstructure of interconnected struts (25, 26, 27, 28, 29) is connected to, and is upstanding from, the modules (10a, 10b) to hold the modules (10a, 10b) with the load bearing surfaces (14) co-planar when loaded and during descent but being elastically deformable to permit limited relative flexing movement between the modules (10a, 10b) under the loads applied by parachute opening and on landing to assist in the absorption the energy transferred to the platform.
