The Kármán line lies at an altitude of 100 kilometres (62 mi) above the Earth&apos;s sea level, and is commonly used to define the boundary between the Earth&apos;s atmosphere and outer space.&lt;p&gt;That&apos;s not space. Though it&apos;s an amazing feat nonetheless.</text></comment>

It always surprises me that there is very little precision rocketry or ROV proliferation  amongst the countries and political/religious movements with extreme agendas out there.</text></comment>
