Summary says it all really. I could not find an English news source yet.
NOS Nieuws - Activist landt op terrein kerncentrale
The 1-mile Prohibited area around French nuclear plants has always seemed silly to me. If you wanted to fly into a nuclear plant, the 30-60 seconds warning that this area would give the French authorities would not be sufficient. But a lot of pilots have had the proverbial cup of tea without biscuits with the French authorities for busting it.
What's more, the enforcement seems to be purely based on radar/transponder readout. In a paraglider, or possibly even in a plastic fantastic microlight, with the transponder turned off, you would be virtually invisible.
So I wonder what this is going to do for those prohibited areas. In order for them to be even moderately effective, you'd have to increase them to 5 or even 10 nm. That would give you, arguably, a marginal response time to any threat. But that would make navigating France all the more problematic.
