Max Pearson presents a compilation of this week's Witness History programmes from the BBC World Service.

These include memories of the horsemeat scandal of 2013 from the man who uncovered what was happening. We'll hear analysis of other historical food scandals from expert Professor Saskia van Ruth.

Plus the last passenger off the plane, which landed on the Hudson river in 2009, shares his story.

Also on the programme: secret schools for Kosovar Albanians, nuclear testing in Algeria and teenagers with narcolepsy in Sweden.
