Is it possible to fly an Andean condor?

Well, an Andean condor has a 3 meter wingspan and the tallest, normal humans are on average almost 2 meters tall so it could be possible, but you would have to be light and have a good bond with the condor in order for it to let you ride it.

Basically, I cant see it myself!

I think you will find the question means, like a falconer would, with trained birds of prey. Yes it is possible, I have seen it done on a wildlife documentary.
