Narrative:

Test aircraft and chase were cleared for unrestr climb to 15000 ft overhead nfw through the class B airspace. The plan was to continue northbound to 'lm' north working area once complete with checks overhead the airfield. F16 as lead aircraft departed with second F16 as chase in 15 seconds trail. The flight flew a military power 300 kcas r-hand climbing turn back towards the airfield once airborne as per standard profile. Approaching 6500 ft, second F16 called to F16 to 'watch out' during the formation rejoin with lead. Second F16 witnessed a 3 ship of locally based F16's maneuver to miss the flight path of departing flight. The estimated distance to the arriving formation was less than .5 NM. Class B airspace extends to 11500 ft above nfw. Arriving formation had received clearance to enter the class B airspace to proceed to high key for practice sfo's (simulated flameout approachs). F16 and second F16 had received clearance to climb through the class B airspace as per local 'lm' procedures. No radio calls were noted on either tower or regional departure control frequencys notifying the formation of any potential flight path conflict. Once the flight paths were deconflicted, departing flight continued northbound and arriving flight proceeded to high key.

Title: FLT OF 2 F165 OFF NFW ON CLB CLRNC THROUGH DFW CLASS B AIRSPACE TO 15000 FT HAVE A NEAR MISS WITH 3 F16 ACFT.

Narrative: TEST ACFT AND CHASE WERE CLRED FOR UNRESTR CLB TO 15000 FT OVERHEAD NFW THROUGH THE CLASS B AIRSPACE. THE PLAN WAS TO CONTINUE NBOUND TO 'LM' N WORKING AREA ONCE COMPLETE WITH CHKS OVERHEAD THE AIRFIELD. F16 AS LEAD ACFT DEPARTED WITH SECOND F16 AS CHASE IN 15 SECONDS TRAIL. THE FLT FLEW A MIL PWR 300 KCAS R-HAND CLBING TURN BACK TOWARDS THE AIRFIELD ONCE AIRBORNE AS PER STANDARD PROFILE. APCHING 6500 FT, SECOND F16 CALLED TO F16 TO 'WATCH OUT' DURING THE FORMATION REJOIN WITH LEAD. SECOND F16 WITNESSED A 3 SHIP OF LOCALLY BASED F16'S MANEUVER TO MISS THE FLT PATH OF DEPARTING FLT. THE ESTIMATED DISTANCE TO THE ARRIVING FORMATION WAS LESS THAN .5 NM. CLASS B AIRSPACE EXTENDS TO 11500 FT ABOVE NFW. ARRIVING FORMATION HAD RECEIVED CLRNC TO ENTER THE CLASS B AIRSPACE TO PROCEED TO HIGH KEY FOR PRACTICE SFO'S (SIMULATED FLAMEOUT APCHS). F16 AND SECOND F16 HAD RECEIVED CLRNC TO CLB THROUGH THE CLASS B AIRSPACE AS PER LCL 'LM' PROCS. NO RADIO CALLS WERE NOTED ON EITHER TWR OR REGIONAL DEP CTL FREQS NOTIFYING THE FORMATION OF ANY POTENTIAL FLT PATH CONFLICT. ONCE THE FLT PATHS WERE DECONFLICTED, DEPARTING FLT CONTINUED NBOUND AND ARRIVING FLT PROCEEDED TO HIGH KEY.
