Tis one I cannot blame on the gatekeepers. It has been around for at least a century. it is part of the larger reg veda.
1. Is the reg veda real and existing.
2. Are the translations of the alleged vimana accurate in the veda or the figment of someones imagination. There are claims of flying machines,space machines and wars involving atomic weapons.
3. The stories as I have seen them are somewhat technological in nature as they allegedly describe physical devices.
4. The additional link from the wiki place is something different. it is NOT part of the veda at all.
5. What do Indian archaeologists thing of this veda.
6. It should be noted that the late Robert oppenhiemer of atomic bomb fame was claimed to say that after the first bomb exploded he said it was the first at this time (meaning the present). he was a reader of the vedas.
