Creativity and resourcefulness were the early foundations of Israeli military success in the air, rather than technology which, at the inception of the IAF, was generally inferior to that used by Israel's adversaries. In light of the complete Arab theater air supremacy, and the bombing and shelling of existing airbases, the first Israeli military-grade fighters operated from a hastily constructed makeshift airbase around the current Herzliya Airport, with fighters dispersed between the trees of an orange orchard.[13][14] As the war progressed, more and more Czech, US, and British surplus WW-II aircraft were procured, leading to a shift in the balance of power.
