Should all this credit about "Aircraft" be given to the Wright Bros. Or it should be revoked?

If you do some research on this issue, one would realise there were other players who achieved flight, before them. Heavier than air crafts too (still inconclusive on that). But their aircraft was winched and didn't take off by its own self (own power). But that of the French-Brazillian Santos Dumont did.

So, think its part of d american propaganda BS.

What u reckon
