According to Jarosław Wolski[1] the drones that violated Polish airspace last night consisted of two groups:

- Shahed/Geran strike drones that after enterng PL airspace turned south and then west towards rargets in UA, taking a long way to avoid UA defences

- Gerbera decoys that flew in random directions deep into Poland

The Gerberas may've been disoriented by UA electronic warfare, but the Shaheds were definitely intentional.
