History and services of Aloha Airlines

Aloha Airlines, initially founded as Trans-Pacific Airlines in 1946, aimed to compete with Hawaiian Airlines. Starting with just one aircraft, the airline quickly gained popularity and earned the nickname “The Aloha Airline.” It officially became Aloha Airlines in 1958.

Over the years, the airline encountered various challenges, including tough competition in the market, rising operational costs, and external events such as the 9/11 attacks and increases in fuel prices. These difficulties led to financial struggles, prompting Aloha Airlines to file for bankruptcy protection twice—first in 2004 and again in 2008. Despite their efforts to overcome these challenges, the airline had to suspend all passenger flights in March 2008, resulting in employee layoffs.

To cope with the situation, the company decided to sell its successful freight and contract services division to Saltchuk Resources, an established player in the Hawaiian market. This strategic move was made to salvage some part of the business amidst the challenging circumstances.

Event Information: Day, Time, and Area

On April 28, 1988, at 1:25 PM, Aloha Airlines Flight 243 experienced a catastrophic event at Hilo International Airport terminal. The aircraft had already completed three uneventful round-trip flights earlier that day. Before departure, the pre-flight inspection didn’t reveal any abnormalities, and there were no weather advisories for the intended route.

The flight proceeded normally until around 1:48 PM when the airplane was about 23 nautical miles south-southeast of Kahului, Maui. It was at this moment that a section on the left side of the airplane’s roof ruptured with a distinctive “whooshing” sound. The aircraft’s captain felt a sudden jolt and encountered instability, while the first officer observed airborne pieces of grey insulation within the cockpit. The cockpit door broke away, revealing an open view where the upper ceiling had once been.

The extent of the damage was substantial; a large portion of the roof, approximately 18 feet in diameter, had torn off from behind the cabin to the fore-wing area. These events occurred during the flight at an altitude of 24,000 feet (7,300 m), disrupting the normal operation of the aircraft and creating a dangerous situation for everyone on board.

Description of the airplane

It was the Boeing 737-200, which was the 152nd aircraft produced at the Renton assembly Unit. It was delivered in 1969 to Aloha Airlines brand new having registration number N73711. Over its service life, the aircraft had accumulated 35,496 flight hours and nearly 90,000 flight cycles, exceeding the intended design limitations.

The Sequence of Occasions and Causes

At precisely 1:25 p.m. on a typical Thursday, Aloha Airlines Flight 243 commenced its journey from Hilo to Honolulu. Initially, passengers settled into their seats, engrossed in various activities like reading, working, or simply trying to unwind.

Unbeknownst to the pilots, a sudden and significant change in pressure occurred. This caused the aircraft’s floor to rise, breaking numerous floor beams and damaging the cable connected to the left engine. Consequently, the plane started shaking violently, posing a challenging situation for the pilots, Schornstheimer and Tompkins.

Schornstheimer promptly took control of the plane, focusing on stabilizing it and initiating an emergency descent toward Maui. Realizing the extensive damage, he decided against attempting to restore the cabin’s pressure, understanding it would be futile and potentially perilous. Managing the aircraft became even more challenging as it was now flying faster than usual, at around 170 knots, or just over 195 mph. Previous attempts to slow down the plane had only exacerbated the violent shaking.

Finally, at 1:58 p.m., the aircraft landed tensely on the runway of Kahului Airport, with the front landing gear lowered. However, the danger was not yet over. As aircraft rescue firefighters hurried to the scene, a makeshift area was swiftly established near the plane to provide immediate medical care to any passengers or crew members who might have been injured.

Rescue and Emergency Actions

Following the emergency situation involving the plane at Maui Airport terminal, the fire department responded promptly, dispatching five emergency vehicles to assist. Passengers who were able to walk left the aircraft using slides and the back airstair. Once the area was secure, fire department personnel entered the plane to aid the injured passengers still aboard. Remarkably, within 25 minutes, all passengers were successfully evacuated from the plane.

Initially, the flight crew informed the air traffic control service (ATC) about a “rapid decompression” situation but didn’t provide specific details about the extent of the structural damage. The ATC promptly alerted the rescue and firefighting teams, although they didn’t immediately request ambulance assistance. Later, at 13:53, the flight crew confirmed their need for passenger assistance upon landing, which was acknowledged by the ATC. According to police dispatcher records, the “Medic I” ambulance was alerted at 13:58, around the same time the aircraft touched down. The reason for notifying the ambulance late remains unknown. The first rescue team arrived at the scene at 14:05 and called for additional assistance.
