Not strictly LTN, but it's then poorer neighbour Stansted, used to have a Scandinvasion every sunday evening when Caravelles of Sterling, 720's of Maersk and DC8's of Sunair (?) which arrived to ferry bus loads of students etc to the UK. It seemed the busiest time of the week at an otherwise empty STN. Did LTN also have some of these aluminium armadas from Scandinavia ? I realise that UK holiday makers were flown out in several aircraft from LTN on behalf of Pontinental etc, but was the reverse with foreigners arriving en masse to savour the delights of 1970s London, also true ?
