Israel has very good security in its airports. How did the hijackers get on the Air France plane?
They climbed in through the baggage compartment. They pulled a switch that shut down the power of the scanning machines in the airport. They used plastic guns which can't be detected by metal detector equipment. They got on in Greece instead of Israel.
The terrorists allowed non-Jews to leave Entebbe on Air France before their deadline for release of prisoners from Israeli jails. What are like reasons for why they did that?
They didn't want France to turn against their cause. They didn't want the western world to turn against them. They didn't want the non-Jews to see them killing Jews. Idi Amin, the president of Uganda probably didn't want the whole world to turn against him.
The terrorists allowed non-Jews to leave Entebbe on Air France. Why didn't the non-Jewish French pilots get on the plane and fly it home?
They were unwilling to abandon their passengers. They were very heroic They didn't want to make it easier for the terrorists. They were afraid the terrorists would blow up their plane once it was in the air.
