## Analysis (aircraft 2)

N3322L INADVERTENTLY CROSSED THE ACTIVE RWY 04 AT THE TIME N107T BECAME AIRBORNE ON TAKEOFF FROM THAT RWY. A NEAR MISS OCCURRED AS THE CAPTAIN AND 1ST OFFICER OF N107T OBSERVED N3322L ON THE RWY AND MADE A MAX PERFORMANCE CLIMB OVER THE TOP OF N3322L. N3322L WAS ORIGINALLY CLEARED FOR TAKEOFF ON RWY 04 VIA TAXIWAY CHARLIE TO FOXTROT. THE FLT CREW DID NOT MAKE A NECESSARY TURN FROM TAXIWAY CHARLIE TO TAXIWAY FOXTROT. NEITHER ACFT WAS VISIBLE FROM THE TOWER DUE TO REDUCED VISIBILITY.
