..??? I can put one AP in each wing tip, one in the nose, and
one in the tail, and one in the middle? That's 20 links per drone,
bridge those, and you have 10 bridged links. Also possible to
fence them away from each other and wire them together etc,
if you really wanna play games here.

..my experience with isp's, is, set up proxy servers and spam weed
servers, and phase in new customers so your old ones have time to
stuff their disks full and quit DL'ing stuff at 100% pipe speeds. ;-)
Here, my isp sells 400/200kbps and sees right now a 300kbps total
for about 2200 ip connections.

..ok, solar cells and batteries. Hydrogen, makes good lift gas and
fuel. No crew to burn, no need for expensive heavy helium. ;-)

...flashy plastics can be torn off, heavy metal can be milled flat
and replaced with tin foil, cooling fins and fans, with piping for
2 parts glycol 1 water, gasoline or jet fuel as coolant, radiators
and pumps etc.
..power can be fed off solar and fuel cells or generators and fed
straight into AP's or onto pc main boards, so no need for big
ass clunky wall plug power supplies. Etc.
..so, we return to sizes, weights, and power etc requirements. ;-)

..huh? They do support line of sight? 60000ft ~ 20km, that's _up_.
Assuming you are correct about their 20 km signal path loss range,
keep in mind that their 20 km is _along_ the surface, say across the
sea, where the air is nice and thick. Signal loss from your ground
station up to my relay drone, will be proportional to the air density
_along_ the signal path.
..now, pointing you ground station antennas up say at 11 degrees
elevation to point at my relay at say 20km altitude to match your sea
level signal loss, and then down on the other side at a similar angle,
takes you how far? ;-)

..cool, 2 or more drones in the air, and several ground stations etc.
..or, are you setting up _several_ isp's, or are you setting up several
_route_ isp's to serve the _one_ isp you have made the 26 boxes for?

..close, like in "big model airplane carrying pc's" or AP's set up
as bridges. The airframe would be a slow high flying wing with
an autopilot, to make a flying robot relay drone. ;-)

..dunno, but I can beat that satellite with a relay drone. ;-)
..for anything past 99.9% 24/7 service, I say 3 drones minimum, one
airborne in service, one ready for takeoff, and "one in the work shop".
For every additional link serviced, add one airborne relay in service,
and depending on distances to, and between relay loiter points,
service policy etc, consider launching flying spares.
..for your "redundant 2 link or more" argument, that can be anywhere
from one more relay drone in the air, to 4 fully independent drone link
base teams, "2 on each side of the sea", etc. You obviously want to
cross-link between all these, to isolate a single failure, rather than
take down a full lenght link.
..also, consider traditional wifi grids, high altitude relay drones can
join these, and span them, and span several of these grids, and
can form back bone grids. A single point failure becomes less
problematic, as traffic can be re-routed until a new drone is up
and takes over the loiter point.

..yup, failing that, I have http://fmb.no/ipcop/setup-cbq-0.0.5.tar.bz2
which could use a web interface, and a wee linux box to run on to
trottle the bridged links, I would prefer to have the airframe controls
separated from the payload bits, here, we rocket scientists are a bit
