<div class="moz-cite-prefix">I also wonder if they have considered
that when these "loons" reach burst altitude and they start
falling with there payload. What hazard to air navigation will
they present. Have they consulted with ICAO. Weather and science
balloons are used away from air routes however this will conflict
with the idea's getting IP to populated areas. Also weather
balloons are few these guys are going to need a more then few to
get the job done. I guess they could put a transponder on board
but 100W 1090Mhz transceivers are not light and have a large power
requirement. If you ask me if we don't need another spotty
coverage wireless internet service. We already have Globalstar.
;) Perhaps Autonomous UAV's like

According to wikipedia there is no international agreement on
how high above ground national airspace extends but the lowest
suggestions are 20-30km, which is roughly the altitude the
"loons" fly at.<br>
