Abstract
Abstract A signal transmitting steering cable (4, 40, 40') for remotely-controlled flying bodies (1) which, once the flying body (1) has been launched, can be located and disposed of easily. For this purpose the surface layer (44, 46) of the steering cable (4) includes a material which is fluorescent when illuminated with light of a predetermined wavelength range. Preferably, a dye whose emission spectrum lies approximately between 530 and 690 nm is employed as the fluorescent material.
