I just ranked up to where I could buy a Buzzard. I don't really care how cost effective it is, what the hell else am I going to spend my money on? It's not like I can buy a second garage or anything...
Anyway, this mission is a fun one. I'm still a relative chopper noob, but my skills are increasing with each pass.
I also just did Clearing the Cathouse with the Buzzard. Another quick and easy flying mission with good RP, but low money.
Between CCIII, potshot and coveted, there's a quick three selectable single player missions, each of which is very different from the others. Fun to link together.
