Very interesting and daring raid against overwhelming odds.
Quality restrained narration by Lord Ashdown with no needless fanfare and the added bonus of having Colley in it too.
(Britain and) The BBC at its best.

Hasler certainly was made of the right stuff.

I wonder what he thought of the two two raid happening at the same time and of the cost in lives.
Very interesting to read about his later years also.
Hasler later raced the Junk rigged Jester. That chapter and his invention of the self-steering gear is also very interesting.
