Stay low. Reminds me of a story. Knowing the guys who told it, I'll bet it's true.
The Arizona NG uses a major repair station at KFAT (Fresno, CA) for mx on their helos. A certain 3 man crew, who has been together since VN, gets the majority of flights to the station. They sit around a couple three days (doing what, you may ask) and then ferry the chopper back to base.
A long honored tradition, they carry a large ice chest as part of their payload. Ballast, you might say. Anyway, they fly direct at a ground hugging alt. They have to, you see, because they need to see the string of empties to find their way back to base. Long hours waiting on the mx does that...
Sadly, this latest action in Iraq has broken this crew for the 1st time in 20 years. "Horse", if you're out there, man there are some folks who miss you. Call Donna.
