Talk:KLM Flight 608

Possible cause
The aircraft possibly crashed due to CO poisoning of the crew. A number of DC-4's had crashed due to initially 'unknown causes' but after post-mortem of the recovered bodies they were discovered to have high concentrations of carbon monoxide in their bloodstreams. Passenger aircraft of the time used fuel-burning heaters for cabin heating and if ventilation of the heaters became obstructed could lead to poisoning of the passengers and crew. These heaters became obsolete when the jet airliner was introduced, which used bleed air from the engines for cabin heating. — Preceding unsigned comment added by 95.149.173.73 (talk) 09:42, 10 February 2019 (UTC)
