The introduction of crossbows however, can be dated further back: according to the inventor Hero of Alexandria (fl. These aircraft can take off vertically with a light load, or use a ski jump to assist a rolling takeoff with a heavy load. Catapults have been integral to siege warfare since antiquity.

[clarification needed], The size and manpower requirements of steam catapults place limits on their capabilities. There are five historical types of catapults: the mangonel, onager, ballista and trebuchet, using three types of motive force: tension, torsion and gravity. to be winched down into the cocked position. Out of all the designs for catapults, there are 3 categories they all fit into. mid-fourth century A.D.) give us valuable insight into siege engines and siege warfare because they were in the besieged cities.
