Sure Schro, as this is my first experience in a real GW, after some Beginners Scenarios completed.
But anyway, maybe I wasn't facing bk, but found myself with 6 planes in total, with 2 in C checks the week following the first one with positive income, you can understand I was a little bit scared.
On the other side I wasn't planning any idea of spare plane, was just wandering is more experienced players act this way or not.
:-) doubt cleared, now I'm gonna go clearing some others!!! :-)
