Happens a lot on the street I live, we have the little green recycle boxes, when it's windy they all blow down the street along with all the recycling items they contained.
I have about 20 boxes round the back of my house that have landed on or near my property, maybe people will learn not to leave them out overnight in the wind if they keep going missing but maybe not.
Lucky for me nothing has hit my cars, hope you get it sorted ok.
