Another Linton on Ouse story: Winter of '77/78. A Shackleton had diverted in from an SAR incedent, but overnight snow prevented its take off. Although the runway was clear, the snow banks at the edges were too high for it to take off. Several hours of wielding a shovel later by us poor students (cheap labour) filled in the black flag day. However, once we had finished the Shack promptly went U/S (Brake Sack leak). The thaw had set in before it finally departed!
