And as I typed that, John e-mailed me the response....
First item (one item per post) is an incident report on a KC-97L that impacted a flock of geese during departure from NAS Dallas just about 15 miles from where I sit right now -
FLYING SAFETY BRIEFING 12 NOV 69 “ONE YEAR AFTER” 12 NOV 69
RICHARD J. ELLIOTT MAJ GROUP FLYING SAFETY OFFICER
Pilot: L/C Robert W. McDonald
Co-Pilot: Capt Dick Curtis
FE: Msgt Jim White
BO: Msgt Frank Hutchinson
DAWN MISSION 1 NOV 68 - NAS DALLAS TO COMOX C.F.B., BRITISH COLUMBIA
TAKEOFF ROLL AT S1 (LAST POINT THAT A/C CAN STOP ON RUNWAY) PILOT OBSERVED A LONE BIRD RISING FROM RUNWAY. AT S2 (AIRBORNE) HUNDREDS OF SEAGULLS CAME OFF THE RUNWAY. PILOT “BIRDS WE ARE GOING TO HIT THEM, CONTINUE TAKEOFF”.
AIRCRAFT IMPACTED HUNDREDS OF BIRDS AT ABOUT 4 FEET OFF THE GROUND. YAWED TO THE RIGHT. PILOT “JETS, JETS WATCH THE JETS, THEY ARE GOING APE. BOOM OPERATER “J-2 IS ON FIRE”. CO-PILOT “TAILPIPE TEMPERTURE PEGGED”. PILOT “STOPCOCK J-2, GEAR UP, ENGINEER WHICH ENGINES ARE BACKFIRING”
ENGINEER “2,3&4, I’LL TAKE THE THROTTLES YOU FLY THE AIRCRAFT”. PILOT “ROGER, POWER, POWER WE HAVE TO GO”. WITH AIRSPEED 130KTS, LEFT RUDDER BOTTOMED YOKE 90 DEGREES LEFT THE AIRCRAFT WAS BROUGHT UNDER CONTROL. PILOT “GET ALL THE POWER YOU CAN, WE HAVE TO HAVE EVERTHING YOU GOT”. ENGINEER “#4 IS GOING TO FAIL IF I DON’T BACK OFF”. PILOT “OK BUT KEEP ALL YOU CAN”.
DUMPED 45,000# OF JP4. A/C ACCELERATED TO 170 KTS CHECKED FLIGHT CONTROLS AND TURNED TO RIGHT DOWNWIND. A/C WAS VIBRATING LIKE A STALL, BUT WHEN #3 THROTTLE REDUCED THE VIBRATION WAS LESS.
#2 ENGINE QUIT BACKFIRING, #3 BACKFIRED EVERY 10 SECONDS AND #4 CONTINUEIOUSLY. REVERSED #1,2&3 ON LANDING. ROLLOUT WAS NORMAL UNTIL AREA OF BIRD STRIKE. A/C HYDROPLANED LIKE ICE OR SNOW OVER HUNDREDS OF DEAD SEAGULLS. THE AIRCRAFT WAS TAXIED TO THE RAMP AND SHUT DOWN. THE ODOR OF SEAGULLS BOTH INSIDE AND OUTSIDE THE AIRCRAFT WAS OVERPOWERING.
THE MAJOR EXTENT OF DAMAGE WAS TO RIGHT WING AREA AND THE J-2 ENGINE WHICH INCURRED SEVERE COMPRESSOR DAMAGE. NO. 4 ENGINE TURBO SUPERCHARGER WAS PACKED WITH BIRD REMAINS AND COULD NOT BE ROTATED. ALL AREAS SUCH AS OIL COOLERS, AIR ENTRY SCOOPS, ENGINE CYLINDER AREAS, HEATER INLETS AND LEFT PITOT TUBE WERE OBSTRUCTED WITH BIRDS. A PILE OF DEAD BIRDS TWO FEET HIGH AND FOUR FEET ACROSS WERE RECOVERED FROM THE RUNWAY ALONE AND A RUNWAY SWEEPER PICKED UP MANY MORE. HUNDREDS WERE OFF THE SIDES OF THE RUNWAY.
WATCH FOR BIRDS
Items to take - with 3 engines experiencing trouble (2 on one side) and 1 of the 2 booster jets shutdown, the aircraft was just barely controllable and required full rudder and yoke input to counteract initially. Aircraft was extremely heavy and just took off, so airborne safety speed had not been reached when impacts occurred, so this is an indication that at high weights, engine out performance can be marginal.
Second response to follow.
