+1 having a p39 or (insert plane) bonus perk day/week/tour doesn't take anything away from anyone or force anyone to fly a certain plane. Might even prompt someone to fly a little more or reignite a desire to play in someone who is getting bored. I think it would be in HTCs best interest to have something similar to this going on all the time. Throw something new, but simple in every tour while folks wait on the big stuff like new planes and terrains.
