-        Possible lightning strike at 194328 computer time

 

Maintenance

-        Generator failed at 200614 video time.  Video quality degraded as failure progressed.

-        P-static still a significant issue

 

Operations

-        Recommend ground controller provide tactical position of desired target (i.e. your 9 o'clock for 15 miles).  Can pass this onto ATC.
