Which facts do you not beleive? We're on the internet, we can check the news on other languages, not only what's written in the English speaking media. I have the privilege of knowing a few more European languages but even better we can all use Google translate. Let me summarize the facts:

The plane with president Morales and his delegation wanted to fly back to Bolivia from Moscow. It's a plane that simply has to refuel for a trip like that. During the flight four European countries: Italy, Portugal, France and Spain withdraw the permission to fly over, effectively forcing the plane to ground. Spain admitted independently that "they have been given an information that Snowden is on that plane." The president spent more than 12 hours on Vienna's airport.

What do you question then?

I'm not questioning that Morales had to land in Vienna, I'm questioning the reasons behind it, because I haven't seen countries giving "Snowden was on the plane" as a reason to deny airspace.

"European states were told Snowden was on Morales plane, says Spain

Spanish foreign minister declines to say where information came from that NSA whistleblower was on Bolivian leader's flight"

Reuters, today:

http://www.stuff.co.nz/world/europe/8899974/Spain-admits-US-...

"Spain has acknowledged that a US request had led it to delay approving an overflight by Bolivia's president, but said it had given the go-ahead after receiving an assurance from Bolivia that US fugitive Edward Snowden was not on the plane."

The U.S officially had no comment, last I checked.
