USAF 616 - Captured MiG-15bis via North Korean defector, test flown by USAF Gen. Chuck Yeager (Ret.)
While this particular acft wore a number of markings, the vast majority of documentation shows this captured North Korean aircraft in #616 USAF basic livery - test flown by - among other pilots - USAF General Chuck Yeager.
Makes a nice addition to your MiG-15bis if you also download my US-Units English Cockpit (http://www.digitalcombatsimulator.com/en/files/1374710/), as the USAF reports indicate that Yeager and the boys refused to fly with Metric instruments, and instead had US standard altimeters and IAS gauges installed.
