I also believe the Fencer sale is a hoax. 28th december is the "dia de los inocentes" in the spanish speaking world - their equivalent to april fools day.
As I commented in an earlier post....
I see a lot of Argentine posters on the interweb saying this Su-24 story was all a hoax, but I don't buy it. What's 'funny' about getting Su-24s? Where's the 'joke'? If the story was that they are getting Tu-95s, then ok, ha ha, but Su-24s? It's unlikely but not so incredible.
Surely the point of a hoax is for it to be funny, no? Where's the joke in this?
