In the cave temples of Ellora we can see the carvings of Ravana with a flying machine tied to his back. It represents a 1200 years old flying machine which Ravana had used in the era of Ramayana. Figure below represents the same.
It is comparable with our most advanced and fascinating flying devices of modern times called Jetpacks. A 1200 Year Old Vimana - Alien Flying Machine (Ellora Caves)6 Six straps around his waist represent the safety harness through which he has fastened the flying device to his back. Even in modern Jetpack we have six straps through which we can tie the Jetpack to our back. The bird at the bottom represents the bird Jataayu which fought with Ravana while he was travelling to lanka after abducting Seetha. The circular wheel in the image represents a propeller which is similar that used in modern Jetpack.
Modern Jetpack has two propellers, image shown below represents a side view of the flying device, assuming that there is a similar circular wheel on the other side of the flying device this is also very similar to our modern Jetpack.
We can see a horse in the opposite direction of that of Ravana. Looking at the size of horse, in comparison with that of Ravana it doesn‟t seem to be real horse, it is comparable with the horse shaped nozzle through which exhaust gases are thrown out of the flying device in the opposite direction of flight which helps in upward movement of the device. Even in modern Jetpacks we see the two nozzle valves through which exhaust gases are thrown out of the device. The rectangular device above the wheels represents safety roll device which are similar to the ones which are
used in modern Jetpacks.
In the first Figure , we can see Ravana wearing a crown and holding a device in his right hand near his ear. This is similar to the safety helmet which pilots wear and transmission device through which pilots interact with air stations to receive the signals for takeoff or landing. It is described that Ravana had multiple flying machines which he regularly used for traveling to various places and had six airports in Lanka where he used to park these aircrafts.
Ravana might have been interacting with these airport base stations using the transmission device which he is holding in his right hand. Device which he is using in the left hand is something which is comparable with the GPS device which the pilots use even today. This makes us think if such a flying device with technology similar to that of our modern times existed during the era of Ramayana.
April 2014 news article on “Will we soon be riding JETPACKS to work? Breakthrough technology could see the creation of 'highways in the sky'” written by Laura Mears published in “Mail Online Science & Tech” describes in detail about the history of Jetpack and the technology evolution of the same till date. Martin Jetpack is heralded as the world‟s first commercial Jetpack. It utilizes twin ducted fans to create lift. The two carbon Kevlar fans which are situated on either side of the pilot are driven by a bespoke V4 engine.
The ducts are more extensive at the inlet than at the outlet, channeling air through at high speed, and creating enough thrust not just to lift the jetpack and its pilot into the air, additionally leaving an additional 50 kilograms (110 pounds) of thrust extra for quick changes in altitude. The Martin Jetpack can move at about 800 ft (250metres) per minute. The ducted fan configuration and petrol-powered engine empower this jetpack to achieve top paces of 46 miles (74km) every hour, with a respectable flight time of thirty minutes, permitting the pilot to travel distances of up to 19 miles (30km) without expecting to refuel.
Second figure shown above describes the components in modern Jetpack which are in many ways comparable with that of carving of Ravana‟s vimana in Ellora caves. This shows that we definitely have similarity between the Ravana‟s vimana and modern Jet Pack.
