"The US Air Force had sent the Rivet Joint, one of the world’s most powerful surveillance aircraft, to gather intelligence before a hostile operation. The UK also owns three of the planes and last month dispatched one to the North Atlantic to support the seizure of the Marinera tanker, which the US said had transported sanctioned oil for Venezuela.
Equipped with cutting-edge military technology, the Rivet Joint can pick up radar signals, geolocate enemy systems and intercept communications from 150 miles away.
Exactly how it does this is kept strictly under wraps. But we can reveal that an Australian tech company called Appen has performed work for a secretive US military unit, code-named Big Safari, that installs the planes’ tech systems.
Appen recruits gig workers from all over the world to help train AI systems. The company’s latest annual report says it has a workforce of a million people who speak over 500 languages.
Many of these gig workers are paid very little. Some are from countries that have faced attacks from US armed forces. None were told by Appen that they may have been working for the US military."
