It takes an extremely well-conditioned terrorist to be able to slip by behavioral profiling, hence why Israel never has a single incident.
As recently as November 2002 a passenger on an El Al flight was 'overpowered by sky marshals'. He may not have been a hijacker merely a nutcase, but I think it does constitute a profiling failure and hence an incident. Other El Al hijack attempts have been made in the past including the infamous Leila Khaled, but I can't say if that was before or after profiling interviews were started.
