For Freight it really was a dream place for the importers and in particular Tesco that were using MK for the perishables from Africa. I believe the record for on chocks to first truck loaded with LD3's and then truck landside on its way to DC was 8 minutes, that was achieved when the new apron was laid.
The only issues was the runway was not long enough for the fully laden MD 11 which was where the money really was - a 300 mtr extension and the airport would still be busy as a freight / regional pax airport - still all history now and the like of MK dont really exist anymore.
