The DC10-10F is the real rival of the L1011-200F, similar payload and range, 56 to 62 tons and 5 to 6 hs range
The DC10-30F is really not a rival of the L1011, it has almost 80 tons of payload at the same range of the L1011, more fuel burn, more range, etc. Thats why the DC10-30F is a popular cargo aircraft, good payload vs DOC, but you need to put 80 tons of something in it. And it was produced in greater numbers. For what I read from guys who flew the dc10 and L1011, the Lockheed Aircraft is better really, as a plane, but the DC10 was at the right time and at the right moment.
Anyone can help me on the A300B4-200F, I didnt consider that aircraft before but looks good, I need 4 to 5 hs and good volume
