Cone of Silence (1960) Timeline Explained – Every Event in Order

Captain Gort was blamed because the investigation concluded he rotated the aircraft too early during takeoff. Rotating too soon creates excessive drag, which prevents the jet from reaching the necessary flying speed. This pilot error was cited as the cause of the crash that killed his copilot.

The hedge piece found on the undercarriage after the low approach to Calcutta actually originated from Ranjibad, not Calcutta. Captain Clive Judd had flown from Ranjibad earlier and likely encountered the hedge there. The investigation incorrectly assumed it was from Calcutta, but the truth emerged that no hedge exists at Calcutta's runway threshold.

The second crash occurred under similar circumstances to the first, during takeoff from Ranjibad in warm weather conditions. The investigation later revealed that the aircraft's designer had withheld critical information about potential takeoff difficulties in warm weather, suggesting systemic design issues rather than pure pilot error.

The designer withheld information about potential takeoff difficulties in warm-weather conditions. This hidden data meant pilots were not properly informed about the aircraft's performance limitations in higher temperatures, which contributed to the crash circumstances.

The third disaster was averted when a message from the aircraft designer reached a crew preparing to depart in similar warm weather conditions. The designer advised adding eight knots to the calculated unstick speed and keeping the nose wheel on the ground until just before unstick. Following this advice allowed the aircraft to take off safely.

Gort was exonerated posthumously after investigations revealed the design and procedural issues that contributed to the crashes. The withheld designer information about warm-weather takeoff limitations shifted responsibility away from Gort alone, acknowledging that systemic failures, not just pilot error, were to blame.

Captain Clive Judd was in the cockpit with Gort during the Calcutta approach to assess Gort's flying. He lowered the flaps too soon during that approach, which contributed to the unusually low flight path that later led to the hedge being found wrapped around the undercarriage leg.

The check flight was required before Gort could return to active flying duty after the first crash. Captain Hugh Dallas led this evaluation flight to assess whether Gort was still competent to pilot aircraft. Dallas's involvement later became central to investigating the true causes of the accidents.

Charlotte Gort refused to accept the official verdict because she believed firmly in her father's competence and integrity as a pilot. Her stubborn belief in his innocence provided emotional counterweight to the cold, procedural tone of the inquiry, highlighting the human cost behind the tragedy.

The investigation revealed broader problems including how warm-weather takeoffs were handled and how critical design information was withheld from flight crews. The airline and manufacturer faced scrutiny for inadequate communication of performance limitations, exposing gaps in safety protocols that contributed to the accidents.
