How to unlock the Let Them Fly achievement in Midnight Fight Express - Definitive Guide
I found mission 27 (Church) to be the easiest to farm for explosive kills. You have access to RPG weapon and 6 Gas Can throwables to use on 1st part of mission making it a great place to farm.
Going clockwise, starting from top right of map you can get:
Once you get kills, "Restart Level" to save progress and repeat.
