On September 22, 1995, a United States Air Force Boeing E-3 Sentry airborne early warning aircraft, known by its callsign Yukla 27, crashed shortly after takeoff from Elmendorf Air Force Base in Alaska. This tragic incident resulted in the loss of all 24 crew members on board. The aircraft, serial number 77-0354, was scheduled for a training sortie when it encountered a flock of Canada geese, leading to a catastrophic loss of power and subsequent
crash less than a mile from the runway. The events of that day highlight the critical and often unpredictable dangers that bird strikes pose to aviation.
The Ill-Fated Departure
The E-3 Sentry, operated by the 962d Airborne Air Control Squadron, was preparing for a routine training mission. Its departure was scheduled from runway 06 at Elmendorf Air Force Base. Before Yukla 27 began its takeoff roll, a C-130 Hercules transport aircraft took off from the same runway. Unbeknownst to the crew of the Sentry, the preceding C-130 had disturbed a large flock of Canada geese, scattering them in the vicinity of the runway.
As the E-3 Sentry lined up and commenced its departure roll, the crew was unaware of the presence of these birds. The aircraft reached the point of rotation, where the nose wheel lifts off the ground, and at this critical moment, it ingested a significant number of birds into its number 1 and 2 engines. These two engines were located on the left wing of the aircraft, leading to an immediate and severe loss of thrust on one side.
The Struggle for Control and Inevitable Crash
Following the bird strike and the sudden loss of power in both left engines, the crew of Yukla 27 initiated emergency procedures. They began to dump fuel, a common practice to reduce aircraft weight for an emergency landing. Simultaneously, they attempted a left turn, aiming to return to the airfield for an emergency landing. However, the situation was dire.
With a full fuel load at the time of takeoff and the complete loss of two engines on the same wing, the aircraft was severely compromised. It was unable to maintain altitude, struggling against the combined effects of reduced thrust and heavy weight. The E-3 Sentry managed to reach a maximum altitude of only 250 feet before it began to descend rapidly. Just 42 seconds after its rotation, the aircraft crashed into a hilly, wooded area. The impact was violent, leading to an explosion and the complete destruction of the aircraft, tragically killing all 24 occupants.
The Aftermath and Investigation Findings
The crash site was located less than a mile from the end of the runway, a stark reminder of how quickly the disaster unfolded. The investigation into the accident concluded that the probable cause was indeed the ingestion of Canada geese into the number 1 and 2 engines. However, the investigation also identified contributing factors that played a role in the tragedy.
These factors included insufficient efforts by the air base to deter birds from the airfield, suggesting a lapse in wildlife management protocols. Additionally, the air traffic control tower failed to report the presence of birds on the airfield to both the Sentry crew and airfield management. This lack of communication meant the crew was not forewarned of the potential hazard. The investigation also detailed the sequence of events during impact: the aircraft struck the ground nose first, slid to the top of a hill where the tail section broke off, then rolled over as it cleared a second hill. The fuselage broke apart during the roll, with the outboard right wing impacting on the left side of the wreckage, the right-hand wing breaking off, and the rotodome section impacting on its back, leading to the complete breakup of the aircraft. The wreckage path indicated the aircraft flew approximately 0.8 miles before hitting trees and then another 0.45 miles before crashing in a fireball.
