Held Prisoner in Hampton Roads

On an AFN "commercial" Lt. Gen. Mark P. Hertling, Commanding General of U.S. Army Europe, reflected on the fact that his father flew a B-27 during the 2nd World War. 

Nevermind that there never was a B-27.  We had the B-17 Flying Fortress, B-24 Liberator, B-25 Mitchell, B-26 Martin Marauder and B-29 Superfortress.
