Similar to a problem in Oz many years ago in which the crew performed a series of rolls and yaws to keep the thing flying while they clawed a bit of height sufficient to give them time to figure out a recovery.
As I recall not a cg problem but the pitch up was similar. With a cg problem the stability considerations make life very difficult for the non-FT pilot who has no familiarity with the differences.
The pilot is a PPRuNe contributor and there are posts on the event although I can't locate them at the moment. Will contact another contributor who will almost certainly be able to provide a link.
