A good story not known by many - S.L.
The only four (4) airplanes Israel had when the war of independence began were smuggled from the Czech Republic. They were German "Messerschmitt 109s. They were assembled overnight in Tel Aviv and were never flight tested. This is a short video about their pilots.
Contrary to popular perception - by the people who do not know history - the United States government's assistance to Israel during the war of independence was non-existent.
Americans were not allowed to join the fight and an arms embargo was established and enforced by the FBI.
At the same time Arab armies were very well supplied by the same countries who maintained arms embargo against Israel and of course had great advantage in manpower.
