I use to fly with an old flight engineer on a DC6 who told lots of stories of his time flying the Biafra airlift. He flew for a Belgium operator Trans air i belive saying he was glad that he was flying a six not the seven. Because the turbo compounds on the seven lit up the sky on take off showing the Mig pilots shoot here!
There were British pilots also flying for the other side flying the Fields converted DC4 bomber & the Migs.
