I have been thinking about weather or not hooking a winch to a magnet, then hooking the magnet to a missile, then firing the missile for propulsion would be possible. I do not know if a missile would even attach a magnet and if it did there would be a 50/50 chance of an explosion.
Could be possible without explosion if it's slow enough for has a shock absorber between the magnet and missile. Also the missile should have 0 proximity detonation and also cant explode on collision
