109.5 mcs 1206:36 SLICK FOUR ZERO ZULU IS A HUNDRED FIFTY FEET LEFT OF COURSE PASSING THE MIDDLE MARKER FIFTY FEET ABOVE TWENTY FIVE FEET ABOVE GLIDEPATH.
No additional radar advisories appear on any of the communications recordings after the flight had passed the middle marker.
The PAR controller did not attempt to contact the flight after it passed the middle marker; however, he said he contrinued to monitor the aircraft's position and did not observe the aircraft's radar target leave the glide slope at any time until he observed the aircraft target climb to about 200 feet in a slight left turn when in the vicibity of the approach and of the runway. He then notified the coodinator that Slick 40Z was making what appeared to be a missed approach.
At about 1207, a loud sound was heard by controllers in the tower cab and approximately 10 seconds later the aircraft was observed as it slid, out of the fog bank, on fire. It came to rest at the southcast corner of the intersection of runways 28L and 1R. The local controller recorded the time of the accident on the 120.5 mcs. tape as 1207:30
An intense fire engulfed the aircraft and the cockpit filled with smoke. Three passengers and the flight engineer escaped. One passenger could not recall how he exited. The other two and the flight engineer went out the right crew entrance door, although it could not be raised more than 12 to 14 inches because of jamming by the opened smoke removal window. This smoke removal window had been opened by the flight engineer before the door was raised. Attempts by fireman to open this crew door further and the left front cargo door from the outside were unsuccessful. The captain, copilot and two passengers died of thermal burns and smoke inhalation.
Initial impact of the aircraft was made upon the approach light structure 1,170 feet from the threshold of runway 28R, approximately 11 seconds after passing the middle marker. The threshold of runway 28R is at 13 feel m.s.l. Damage occurred to both main and nose landing gears when they contacted the approach light structure which projects outward along the runway 28R centerline, into the bay a distance of approximately 3,000 feet. These lights are at 18 feet m.s.p. in groups or stations at 100-foot intervals, and they are numbered 1 through 30 out from the runway threshold. The aircraft struck approach light stations 11 through 5.
The climb angle from the point of last contact with Station 5 to a radar observed point 200 feet above and 950 feet past the runway threshold was 7.5 degrees. From the apex of the ascent to first ground contact the angle was 12.5 degrees. The distance from the middle marker to the ILS touchdown point is 4,716.5 feet. The distance from the initial impact point to the ILS touchdown point is 2,304 feet.
