Hey HTC,
I was awarded the "kill a plane with a bomb" award.
The situation was I had been hit and lost a wing from an 88 at a V base. As i spiraled down towards the field I dropped the last egg from my spixteen hoping for a miracle kill as i was on my way to a grim death anyhow. The 500 pounder hit the ground a fraction before i did and I got the achievement on myself. Perhaps remove own kills or own damage from triggering the achievement?
Pretty sure the achievement was not designed this way.
<S> Tracers
PS: If you are gonna have achievements may as well award perks for em (0.5) or otherwise they are kinda pointless.
