What was in El Al plane ? : Following revealation that the 92 Amsterdam crash has led to health problems among rescue workers and residents, the Dutch Parliament opened its first formal inquiry into the crash, which had occured shortly after the Boeing 747 took off from Asterdam's airport en route to Tel Aviv. Even today, the mystery of the plane's cargo is not solved. When it was revealed by the newspaper NRC Handelsbald that elements needed to make sarin were on board, the Israeli government said the chemicals were destined for the Institute for Biological research in Ness Ziona, south of Tel Aviv, whose work is secret. Yet a further 20 tons of the 114-ton cargo are unidentified, and the relevant travel documents are missing.
