I remember when 1(F) and 20(R) were both located at Wittering during the 90s. It was an incredibly tight squeeze even then, and that's before Witt became the A4 hub that it is today. Where exactly will JFH put an extra 2 front line sqns at Wittering? And when they do shoehorn themselves into the tiny space that remains, who will get priority in the circuit - the OCU or the front line units? (this was always a huge issue in the past).
