4 December 1958. First flight of the Baade 152 (Dresden 152, VL-DDR 152 or simply 152), first German jet passenger airliner. Designed and manufactured by East German aircraft company VEB Flugzeugwerke Dresden.
Doesn't look too much like a converted bomber so I researched it a bit....
"The Baade 152 represents the final development in the Junkers aircraft family which ended with the "development planes" (Entwicklungsflugzeug – EF).
Its development drew upon the OKB-1 150, an aborted bomber that was developed in the Soviet Union with assistance from captured German scientists.
The Baade 152's basic configuration shares many similarities, including shape, size, wing-area, landing gear configuration, empty weight, range, altitude, speed, power per engine, and double-engine cowling arrangement with the American-built Boeing B-47 Stratojet, a bomber/aerial reconnaissance aircraft which entered service with the United States Air Force during 1951.
Work on the Baade 152 formally commenced during 1955."
