Tracing the Buccaneer's boundary-layer-control flaw

Where did Foxo learn about the design flaw in the Blackburn Buccaneer's boundary-layer-control system?

Through reading and a family friend who worked with Buccaneers and later helped investigate the problem at his own expense.

Foxo learned about the Buccaneer's boundary-layer-control flaw through reading and conversations with a family friend who had worked with the aircraft. The friend also joined a group that paid for its own investigation in the 2000s. Foxo withholds the person's name because permission to identify him has not been given, and says he is writing a book. The answer establishes the basis of this account without describing the mechanical failure in detail. A later comment says boundary-layer-control differences were among several wing problems, including the extended wingtips.
