Interesting, I read an article while I was there, on Channel News Asia (a Singapore government-run news organization) that mentioned the specific planes they are using that currently no one else had at the time. I cannot remember what they were, but perhaps I bought into the spin too much, a victim of the propaganda? I guess it makes sense they wouldn't have exclusive technology since they are probably too small a nation to be manufacturing their own cutting edge fighter jets, so now I'm wishing I could dig up whatever it was I read.
