INFORMATION:

History : the Berkshire / Wiltshire groups assembled and flew toward a beacon called 'Austin' (I think it is near Salisbury).The other groups from RAF Merryfield, Upottery & Exeter assembled over beacon 'Ada' (near Axminster). They then came together at 'Elko' at Badbury Rings, Dorset, near to RAF Tarrant Rushton.
