Détails:
TWA Flight 128 departed Los Angeles at 17:37 for a flight to Greater Cincinnati APT. The crew reported over the Outer Marker at 20:56 and were cleared to land, straight in, on runway 18. The aircraft contacted trees at a point 9357 feet from the approach end of the runway, 429 feet right of the extended centerline at an elevation of 875 feet msl. The aircraft skidded and disintegrated, ending up 6878 feet short of the runway.
The visibility was 1,5 miles in light snow. The ILS glide slope, runway approach lights and Middle Marker weren't operational due to runway construction work.

PROBABLE CAUSE: "An attempt by the crew to conduct night, visual, no-glide-slope approach during deteriorating weather conditions without adequate altimeter cross-reference. The approach was conducted using visual reference to partially lighted irregular terrain which may have been conducive to producing an illusionary sense of adequate terrain clearance."
