Changes in Unlocks?

Is it my imagination or have they made many of the usual airports or the ones nearby much harder to unlock this week?

Everywhere I go, they're wanting weird military type catches in metro or rural/suburban areas, gliders, Chinooks, even airships and balloons.

It's really crazy over much of Europe.

I am scratching my head a lot and oddly, I don't really want to play this week.
