Key safety issues

🔥
Fire and smoke
Fatal harm is reported as linked to smoke inhalation, with later reporting identifying carbon monoxide as the fatal agent.
↘️
Basement risk
Many victims were reported in the basement/lounge area, showing the danger of smoke travel in multi-level venues.
🚪
Escape uncertainty
Witness reporting and later court coverage included conflicting information about alarm raising and emergency-exit usability.
⚖️
Cause disputed
Electrical overheating appears as a repeated hypothesis, but the exact cause and origin were not treated as fully settled in court reporting.
⚠️ Research handlingDo not flatten this into a neat single-cause story. The reliable position is: fire, toxic smoke, 43 deaths, and several unresolved or conflicting details.

Conflicting information

The following points should be retained as disputed unless stronger primary material is later found.

Disputed Detail
Number of injured people.

The record contains conflicting accounts, so this should not be treated as settled fact.

Source 1

Los Angeles Times reported three others hospitalised with serious smoke inhalation.

Source 2

El País reported Lourdes Pérez Pérez as the only injured person, recovering at Hospital Miguel Servet.

The verified sources conflict. Reported injuries should therefore be recorded as: one injured according to El País; three hospitalised according to Los Angeles Times. (Los Angeles Times)

Disputed Detail
Toxic agent.

The record contains conflicting accounts, so this should not be treated as settled fact.

Source 1

UPI’s report said civil authorities were quoted as saying smoke apparently contained hydrocyanic acid.

Source 2

El País reported on 17 January 1990 that carbon monoxide was the fatal agent and that the hydrocyanic-acid hypothesis had been ruled out by laboratory analysis.

Later toxicological reporting supports carbon monoxide as the verified fatal agent, but the earlier hydrocyanic-acid report should be retained as a contemporary conflicting claim. (upi.com)

Disputed Detail
Number of people inside.

The record contains conflicting accounts, so this should not be treated as settled fact.

Source 1

Los Angeles Times reported about 130 people were inside.

Source 2

Heraldo’s retrospective says early information put about 70 people in the room, while other later sources also mention figures up to 130.

Exact occupancy at the time of fire is not verified. (Los Angeles Times)

Disputed Detail
Exact origin / cause of fire.

The record contains conflicting accounts, so this should not be treated as settled fact.

Source 1

Los Angeles Times reported the cause was unknown but an electrical fault was suspected.

Source 2

The 1992 El País acquittal report says the court could not determine the cause or origin, while also reporting an expert view that the origin was electrical cable overheating above the plaster ceiling.

“Electrical fault / overheating” is a repeated hypothesis, but the exact origin should be treated cautiously. (Los Angeles Times)

Open points

These details were not verified from the available source set.

Not Verified
Exact street number of the Flying discotheque.
Not Verified
Full official building plan or licensing file.
Not Verified
Final official fire-investigation report.
Not Verified
Exact number of occupants inside at ignition.
