This interactive is the fullest research to date on the extent of CIA rendition flights of terrorist suspects. It's the result of three years of research by The Rendition Project, a collaboration between academics at Kent and Kingston universities and the NGO Reprieve. It includes more than 11,000 rows of data on confirmed and suspected rendition flights, and other flights from related carriers.

A single interactive graphic, which can be accessed here, shows in great detail the data behind every confirmed and suspected rendition flight, and then – as it's also intended as a tool to fuel further research and digging – a huge number of other flights of the planes linked to rendition. In total, the data powering the graphic runs to more than 11,000 lines.

That means that the graphic's complex, and so we've provided a guide on how to read and interpret it here.

A key caveat is that not every flight contained within the interactive is tied to rendition: some are suspected rendition flights, others are simply flights from planes with tail numbers that were used on suspected rendition flights.

It's also important to note that just because a particular company owned or operating a plane believed to have been involved in rendition, it does not necessarily follow that the company itself was involved or even aware of those activities. In some cases, it's unclear whether the airline companies would have been aware of the purpose of the flights.

A wealth of supporting data and research – including original documents – has been published directly on The Rendition Project's website.
