Honestly, I see the first few months being terrible, but after the novelty wears off, and several of these start to get shot down (hey, they NEED to come down to land, eventually), or have takeoff accidents (seems like a challenging bird to get airborne on a short runway), I just don't see it being that unbalancing.
People say there are so many bomber pilots with 1,000's of perks that they could fly it nonstop. Well, that's also currently true for fighter jocks and the 262, yet for various reasons you don't see those nonstop.
Give it an absolutely massive perk price (500?), deal with two months of whines, and after that you'll finally have something decent for aspiring bomber pilots to save for.
