Listening to 'Midweek' on R4 there was an article on this; this rescue occurred a week before the Penlee disaster, but no-one died(at the time anyway) so it got forgotten.
I remember only too well the Penlee disaster, but , as people are saying, this Bonita disaster is not one I recall. The video is one that had me glued to my chair. Nerves of steel is what those RNLI guys have, all of them!
