Some further thoughts....
Ford where there were Spitfire Spawn point problems was actually a Naval air base. Local RAF fields were Tangmere and its satelite West Hampnett just NW of Tangmere which may not have the spawn probs.
IMHO I thought the convoy was a bit too far from the coast, I believe they would hug the coast to be as far from the French coast as possible. That would have made it easier to find it
Someone said you were moving the action nearer to Calais next Sunday but it would be nice to keep Tangmere in

One of their Sqdns were involved in intercepting 18 Ju88s of II/KG54 on the way to hit RAF Odiham and 601 intercepted 23 Bf110s of V/LG 1 on their way to attack Portland.
