In 2008, Cruickshank and Krack trained David Blaine for his appearance on The Oprah Winfrey Show in which he stayed underwater for 17 minutes.[5] PFI Team was responsible for the education and training of David Blaine as well as his safety during the whole event acting as support divers. As David ran into problems with his stunt PFI Team members reacted and pulled him out of the sphere.
