Does anyone know what it is? I would be really interested


*UPDATE*

My investigations were interrupted when  I received a phone calling telling that these were military planes and no further questions are needed. Seems odd to me that in the Finnish military website there was not any info about training going on, as there usually is. But if that is what the government wants us to believe, we have to accept it.
