Inactive Fuel Rat here.
What they are saying is dead on. We will do what we can to rescue you, and the skill of some of the Rat's pilots is second to none. (I won't claim that of myself. But one of The Rats usually holds the Bubble -> Colonia speed record.)
The number of stories you end up with ratting is amazing... it is a wonderful thing to do. Especially when you have it all in Elite. Why not help others. Rescue can pretty challenging. And losing a rescue... really sucks :( (Code Reds - They are out of fuel, and on O2.)
