Mass-hysteria isn't just coincidence, it feeds off itself.

The 4 other airports were all in DK, where it's top of the news and where everyone is talking about it. Not in other countries.

I think mass hysteria is too perjorative. We have a lot of suspicious data points, but then a new data point turns up (early lights were a false alert) which suggests that the data generating process may be pretty biased.
