As an eager apprentice in the early 80s I was involved with a Boeing mod team that made extensive Slat/flap modifications on in-service 757s. These mods were so extensive that a full CAA flight test was required afterwards. I was fortunate enough to be on one of them. Full stalls on one engine out over the North Sea were quite interesting.
I assume this was due to a problem with the initial design.
