This is an excellent thread!
Luton Anorak's picture of 31st December 1978 brought back memories. We operated LTN NAP LTN in Monarch 1-11 G-BCXR that evening. Delayed by the snow, we busted a gut in a vain attempt to get back before midnight. Had Radio 2 tuned on one of the ADF's to hear Big Ben chiming midnight as the passengers disembarked. Happy Days!
