MISS DEEDS BACK FROM DUREN

 The Me109s use the vertical to get onto the Spitfire's tail - and it breaks off.

 Both Me109s come in from the std aft - one manages to engage but does no damage - both break off.

The second Me109 closes in but is driven off in part by other B-17s in the formation.

Crew land safe and are on the next mission to Wilhelmshaven.
