The Americans favoured a "pilot in the loop" technique, with improved aids for the pilot, over the fully automatic system preferred in the UK. In 1961, to gain experience with "the BLEU automatic landing system" the FAA sent a Douglas DC-7 to RAE Bedford for the system to be installed and tested. After that and further tests on return to Atlantic City, the FAA were convinced and thereafter strongly supported a fully automatic solution to the all-weather problem which later was adopted internationally.[37]
