Interesting old thread. I flew on one of the Rombac 1-11s in 1987. It was YU-ANS, on a damp lease (along with several sister ships) to Adria Airways from Tarom. I went to Ljubljana and back from Leeds Bradford. The aeroplane itself was only three years old at the time and was pleasant and comfortable, just a little dated inside. Outside, the only changes were substituting the Tarom logo and titles for those of Adria, plus giving the aircraft a Yugoslav registration. It was a hot day in Leeds for the outbound flight and it seemed to take forever to become airborne off RW32.
