Oh yeah the Kings,
I remember them from the USA back when I was there trying to jumpstart a flying career.
They put out a series of video tapes for the US ATPL exam. What a bloody farce! The exam books are freely available in the US with the ACTUAL questions in them!
These tapes were just John and Martha going over the questions. Very little theory involved from memory and designed to pass the exam over a weekend or so.
Now I am not trying to denegrade the kings but CASA really has lost the plot!
