Former
Ben Gurion security chief,
Rafi Sela, gave an interview to the Swiss German News portal
Watson, making the following points (in German) :
a) no engine explosion
b) smuggling a bomb on board is incredibly easy,
in the U.S. too
c) there is no hope checking efficiently cabin bags
d) better check pax and airport employees behaviour
e) cameras and computers can sort out 80% of the people having access to the A/C
f) halting, searching and asking the 20% remaining brings more results than shoeless pax or forbidding a more than 50 ml bootle of water
The
interview might be biased because Rafi Sela earns his living in the security business, but it's worth reading if you can do it in German.
