any skydiver that doesnt want to know their pilot is a fool, i have been jumping for 4 years and i make it my business to know who i trust to get me to height
as mentioned earlier most of the better jumpers look after their pilots, as to earlier comments of leaving skydivers 300km away whilst you drive away, you forget that some skydivers are also pilots and all it does is show your lack of professionalism.
if you make some effort most jumpers will too!!!
