First ever self propelled flying device known as *flying pigeo | DailySciencePost

First ever self propelled flying device known as *flying pigeon* by *Archytas* 428 BC. The naming of this device came from the fact that it resembled the shape of a pigeon: wings on either side and a pointed front like a beak. The pigeon contained an opening at its rear which was connected to a heated boiler. The steam produced by the heated water caused an increase in pressure that produced the force required to eject the pigeon, which was reported to fly for several hundred meters.
