Narrative:

Arriving air carrier X on vectors to downwind runway 8L was issued clearance to descend from 10,000'. The vector heading placed air carrier X on a track that would cross the runway 8R departure corridor 1 to 2 mi south of that runway. Fgt Y departed runway 8R on the alana 3 departure with approval to climb 'unrestricted' to 16,000'. The alana 3 departure clears departing aircraft to 5000' and to expect climb to requested altitude from departure control. With this restriction lifted fgt Y were now cleared to 16,000' without leveling off at 5000'. Seconds after air carrier X crossed over the runway 8R departure corridor, the pilot reported 'propwash from the fgt's'. No radar returns from fgt Y were yet observed. The first radar plot on fgt Y showed the lead aircraft climbing out of 14,900', approximately 4 mi south of runway 8R on a southbound track that had crossed over air carrier X inbound track. A maximum effort climb was made by fgt Y so as to arrive at their filed altitude of 16,000' within 6 mi of the departure runway. A near midair collision report was filed by the crew of air carrier X. In routing air carrier X across the departure corridor within 2 mi of the departure runway, and considering the altitude of air carrier X, vertical separation was anticipated to be maintained as the aircraft's paths were to cross. No knowledge of a maximum-effort climb by fgt Y was had, nor was it anticipated. Earlier fgt departures that morning were flown with a more standard and far less extreme climb profile. Supplemental information from acn 117022: we were en route from san francisco to honolulu on july xx, 1989. Approaching oahu, we were vectored from bambo, an entry point on the maggi two arrival, on a heading of 240 degree and assigned an altitude of 10,000 MSL. This heading placed our flight almost directly over honolulu airport. At this point we noticed an fgt in a vertical climb at our 11:30 position flying through our altitude about 1/2 mi distance. This fighter was followed shortly afterward by a second fgt at our 12 O'clock position and less than 1000'. No evasive action was required as the fighters were through our altitude before we had time to react.

Title: ACR WAS VECTORED OVER THE DEP END OF THE RWY AND CAME IN CLOSE PROX TO A DEPARTING FGT CLIMBING UNRESTRICTED.

Narrative: ARRIVING ACR X ON VECTORS TO DOWNWIND RWY 8L WAS ISSUED CLRNC TO DSND FROM 10,000'. THE VECTOR HDG PLACED ACR X ON A TRACK THAT WOULD CROSS THE RWY 8R DEP CORRIDOR 1 TO 2 MI S OF THAT RWY. FGT Y DEPARTED RWY 8R ON THE ALANA 3 DEP WITH APPROVAL TO CLIMB 'UNRESTRICTED' TO 16,000'. THE ALANA 3 DEP CLEARS DEPARTING ACFT TO 5000' AND TO EXPECT CLIMB TO REQUESTED ALT FROM DEP CTL. WITH THIS RESTRICTION LIFTED FGT Y WERE NOW CLRED TO 16,000' WITHOUT LEVELING OFF AT 5000'. SECONDS AFTER ACR X CROSSED OVER THE RWY 8R DEP CORRIDOR, THE PLT REPORTED 'PROPWASH FROM THE FGT'S'. NO RADAR RETURNS FROM FGT Y WERE YET OBSERVED. THE FIRST RADAR PLOT ON FGT Y SHOWED THE LEAD ACFT CLIMBING OUT OF 14,900', APPROX 4 MI S OF RWY 8R ON A SBND TRACK THAT HAD CROSSED OVER ACR X INBND TRACK. A MAX EFFORT CLIMB WAS MADE BY FGT Y SO AS TO ARRIVE AT THEIR FILED ALT OF 16,000' WITHIN 6 MI OF THE DEP RWY. A NMAC REPORT WAS FILED BY THE CREW OF ACR X. IN ROUTING ACR X ACROSS THE DEP CORRIDOR WITHIN 2 MI OF THE DEP RWY, AND CONSIDERING THE ALT OF ACR X, VERTICAL SEPARATION WAS ANTICIPATED TO BE MAINTAINED AS THE ACFT'S PATHS WERE TO CROSS. NO KNOWLEDGE OF A MAX-EFFORT CLIMB BY FGT Y WAS HAD, NOR WAS IT ANTICIPATED. EARLIER FGT DEPS THAT MORNING WERE FLOWN WITH A MORE STANDARD AND FAR LESS EXTREME CLIMB PROFILE. SUPPLEMENTAL INFORMATION FROM ACN 117022: WE WERE ENRTE FROM SAN FRANCISCO TO HONOLULU ON JULY XX, 1989. APCHING OAHU, WE WERE VECTORED FROM BAMBO, AN ENTRY POINT ON THE MAGGI TWO ARRIVAL, ON A HDG OF 240 DEG AND ASSIGNED AN ALT OF 10,000 MSL. THIS HDG PLACED OUR FLT ALMOST DIRECTLY OVER HONOLULU ARPT. AT THIS POINT WE NOTICED AN FGT IN A VERTICAL CLIMB AT OUR 11:30 POSITION FLYING THROUGH OUR ALT ABOUT 1/2 MI DISTANCE. THIS FIGHTER WAS FOLLOWED SHORTLY AFTERWARD BY A SECOND FGT AT OUR 12 O'CLOCK POSITION AND LESS THAN 1000'. NO EVASIVE ACTION WAS REQUIRED AS THE FIGHTERS WERE THROUGH OUR ALT BEFORE WE HAD TIME TO REACT.
