Love your reference to CDD! Takes me back, and made me think, when did Castle Donington airport get it's IATA 3 letter code changed from CDD to EMA, and what was the history behind the code CDD? Was it extant before the new airport opened when the field was RAF Castle Donington?
Reading your summary, the BHX operations of MATO I believe in the early days were on Spanish DC6s and DC7s, but after 15/33 was extended big news was the arrival of Spantax with their Coronados which, again, if I recall correctly were advertised as doing BHX/PMI in something like 1hr50mins. MATO was the forerunner of MATO Jetway which evolved, I believe through acquisition into Ellerman Sunflight.
