revisiting the Turkish attack helicopter competition

if i remember right..

they chose an upgraded version of the 60s era Cobra over the Mongoose, Apache, and the 2 tandem seat Hokum built with Jewish assistance.

and then they suddenly dumped the Cobra for the Mongoose because its higher up in the food chain

so was there any data made available from the preliminary evaulation of the helicopters?
what made them switch from cobra to mongoose
