C'mon SAS, what happened to your famous sense of perspective! SFENA (the thing in the 212 'afforded' by BHL) was intended as a stabilisation system for an unmanned article with a flight profile of short duration usually ending in the destruction of the said vehicle AFAIR. My latest office has SFENA in it but after becoming Sextant Avionic then Thales, now part of EADS. Hopefully the SFENA bit won't remember the short duration-destruction aspect.
