Certain governments are always talking about equipping various rebels, in other countries mind you, with weapons.
Leaving aside the moral malaise of the global arms business, there is a huge danger that proliferation of advanced weapons may result in their capture and later use against civilian targets.
Such missiles in the wrong hands are particular a threat to civil aviation.
Today’s invention is therefore a shoulder-launched rocket weapon with a number of tilt switches embedded in it.
These can be set during manufacture to allow the system to be used only against ground-based targets…ie with inclination and declination of only a few degrees.
This arrangement would offer a simple way to significantly lessen the potential threat to any aircraft.
