I experienced another full evening of flying in the MA with no CTD's.  The session involved flying in P-38's, an Me 262, La-7's, and P-51B's.  Fights occured over a fleet, a CAPped VH (V3) and also included multiple attacks on bomber formations.  Numbers (total) were between 160 and 200 on the ND Isles map.
