A lovely sunny day with a light easterly wind, it was a cold start with the ground frozen underfoot. It was soarable 2-4knots to 1700ft cloudbase. The tug was out in the afternoon after changing the retractable towrope. Above the inversion it was beautifully clear. The airfield started cutting up badly after the top inch thawed over the frozen subsoil. Rowan and Matt were practising the patter for BI training.
