Investigation Summary
On the evening of January 23, 1982, Flight 30 was conducting a non-precision instrument approach to Runway 15R at Logan International Airport, having originated in Oakland with a scheduled stopover at Newark. The runway was covered in ice, a condition that had been reported as 'poor to nil' by a Delta Air Lines flight just 35 minutes prior. However, this critical information was not relayed to the World Airways crew, who were instead told braking action was 'fair to poor.' The DC-10 touched down approximately 2,800 feet beyond the displaced threshold at an excessive airspeed, partly due to the captain's reliance on the autothrottle system in turbulent conditions. Upon realizing the aircraft would not stop, the crew steered the plane away from the approach light pier, causing it to skid into the 30°F waters of the harbor. The cockpit and forward galley separated from the fuselage, submerging the first row of seats. The two fatalities, Walter and Leo Metcalf, were ejected from the aircraft and are presumed to have drowned; their bodies were never recovered.
Final Conclusions
The NTSB determined the probable cause was the minimal braking effectiveness on the ice-covered runway, combined with the failure of airport management to properly assess and ensure runway safety. Contributing factors included the failure of ATC to transmit the most recent pilot reports (PIREPs) of 'poor to nil' braking action and the captain's decision to maintain excessive airspeed during the approach. The NTSB also highlighted systemic issues, such as the lack of standardized procedures for measuring runway slipperiness and the absence of regulations requiring operators to correlate braking effectiveness with actual stopping distances on contaminated runways.

Systems & Failure Modes
Autothrottle Speed Control System
The captain maintained an excessive airspeed by relying on this system during the approach, which contributed to the long touchdown.
Braking Action Reporting
The system for conveying runway friction was found inadequate, as 'fair to poor' reports did not reflect the 'nil' braking reality.
Interesting Facts
- 01The aircraft was a McDonnell Douglas DC-10-30CF manufactured in 1980.
- 02The two fatalities were a father and son who had switched to the flight at the last minute.
- 03The water temperature in Boston Harbor at the time of the crash was 30°F (-1°C).
- 04The aircraft touched down at an excessive airspeed derived from the autothrottle speed control system.
- 05The nose section came to rest 110 feet left of the extended runway centerline.
Safety Actions & Advisories
Runway Friction Measurement
The NTSB recommended that the FAA require airport management to measure runway slipperiness using standardized procedures and criteria.
Contaminated Runway Performance Data
Recommendations were made to provide flight crews with data to correlate braking effectiveness with actual aircraft stopping distances.
