That's what I've heard from the news:
Flight AF111 had to make a diversion after airspace over Kazakhstan and Kyrgyzstan was closed for at least 30 minutes for the launch of a Russian Soyuz space rocket, an Air France spokeswoman said.
Don't know exactly but I'm sure there had to be an appropriate NOTAM. Anyway, no idea why this made news: no actual fuel emergency, just a diversion for some uplift. Just because it's a super?
