An interesting link on Private Flying to an I/F emergency on a North East CV240 many years ago.
An absolutely unsettling read and a situation that none of us would ever want to experience ...
Thread is here.
A definite advert for keeping one's cool and not admitting defeat in the face of near certain failure ... I cannot find any corroborating links .. even if the tale is fable, the story still has a useful moral to tell.
