It most certainly is not. It is the chance of a UAS happening to an aircraft (much less than 1 ie a very small number) multiplied by the chance of an aircraft taking off with the pilot covers on (also a very small number, less than 1) multiplied by the chance of that happening to the same aircraft (another small number less than 1) multiplied by the chance of it happening in the same 24 hour period (one more very small number less than 1).
