Court Line performed Ground Handling for Dan Air in the early days of Dan's BAC111 and Comet Operations out of Luton. I can remember the load sheets being produced in Court Line's traffic office by the tower and the occasions when the fuel carried by the Dan Comets certainly exceeded the amount shown on the load sheets.I suppose it was cheaper to tanker up at LTN than elsewhere. Nevertheless the Comets still lifted off the runway with ease often climbing like a rocket.
