Here are some useful excerpts:<br>"<br>The 10 cubic metre Skyhook Helikite is able to fly
to thousands of feet in winds up to 50 mph lifting a payload of 5kg.<br><br>Helikites are designed for foul weather deployment and foul weather
flight. Even the largest Skyhook Helikites can be launched and retrieved
in all the winds that they can fly in. So deployment and flight can
occur safely in winds up to 50 or 60 mph.<br><br>The new Cased Helikite Aerostat Maintainable Platform (CHAMP) (see
products section) allows the deployment of a 10 cubic metre Skyhook
Helikite within 30 minutes. The unique part of the CHAMP is that it also
includes an excellent Helibase with top cover thus also creating a
permanent, safe base for the Helikite - not just a minimal launch
platform.<br><br>Helikites can even be launched and recovered remotely - with no people
present at all. They are simply winched off or onto the Helibase. <br><div class="HOEnZb"><div class="h5">"<br><br><br><div class="gmail_quote">On Wed, Oct 3, 2012 at 10:37 AM, Lee von Kraus <span dir="ltr"><<a href="mailto:leevonk@gmail.com" target="_blank">leevonk@gmail.com</a>></span> wrote:<br>
