All good points but forget the HEO's for now - we just need a good 
source of regularly launched easy sats in LEO to augment the few working 
birds we have and replace what we have to as they fall out of the sky or 
just stop working.

God forbid they all got hit by debris and all failed but if that 
happened, what would we do ? Still be harping on about AO-40 and whining 
on about getting another HEO up there!

It will happen (maybe not in my lifetime :-D ) but the LEO's must be 
maintained as that is where we get our source of newcomers from, the new 
AMSAT members who will not fork out the thick end of a large amount of 
wedge for an HEO that might or might not get up there!

Just my two rupees worth
