Boeing Co (NYSE:BA) is in court over the compensation it owes to the families of those who died in a 737 MAX crash in Ethiopia in 2019. The key issue is whether the passengers experienced any pain and suffering before they died.

The crash of Ethiopian Airlines Flight 302 killed all 157 people on board when it plunged into the ground at about 700 miles per hour shortly after takeoff from Addis Ababa. It was one of two fatal crashes involving Boeing’s 737 MAX jets that led to its worldwide grounding for nearly two years.

Boeing has settled most of the civil lawsuits from both crashes, but some families of the Ethiopian Airlines victims are seeking additional damages for the emotional and physical distress their loved ones may have endured during the flight.

Company attorneys cited an expert who said that “the human brain cannot process pain faster than approximately 200 milliseconds” and that “the impact forces were so great that death would have been instantaneous.”

They also dismiss any claims based on what passengers might have felt during the flight as “speculative.”

The lawyers for the families counter that Boeing’s argument is “contrary to Illinois law and defies common sense and fundamental fairness.” Families said that there is evidence of pain and suffering based on eyewitness accounts, cockpit recordings, flight data, medical reports, and expert opinions.

The families said that passengers suffered from fear, anxiety, nausea, chest pain, hypoxia, loss of consciousness, and other injuries as they experienced extreme changes in altitude, speed, and direction during the flight. They also said that passengers knew they were going to die as they heard alarms, saw smoke, smelled fuel, and braced for impact.

The judge will have to decide whether Illinois law allows for pre-impact damages and whether there is enough evidence to support them. The outcome could affect how much Boeing has to pay to compensate the families of those who lost their lives.
