Warren Edward Brady was a 46 year old cabin crew member with British Airways based at Heathrow UK. He had worked for British Airways for 19 years on their Worldwide (long haul) Fleet. On 22nd June 2014, Warren was working onboard a 747 non-stop flight from São Paulo (Brazil) to London Heathrow. Three hours into the flight he went for his break in the crew rest section of the aircraft. Warren went to sleep and never woke up. He was declared dead by a Doctor travelling as a passenger on the flight. An autopsy was carried out on behalf of the Senior Coroner of West London. A cause of death could not be established. The Coroner as a result said that Warren had died from a Cardiac Arrest with a morphological heart. In other words he had a Cardiac Arrest, in spite of a healthy heart. ‘Tissue samples were taken during the autopsy and were sent for further study to Dr. Frank Van De Goot - a forensic scientist in the Netherlands. Warrens heart showed a high number of t-lymphocytes present. This had weakened his heart muscle, a phenomenon that is also known as lymphocytic heart muscle inflammation and a fatal condition of the heart. The same phenomenon had already been discovered in the studies of the heart of British Airways Pilot Richard Westgate and also British Airways Cabin Crew Member Matthew Bass. There are only three possible causes for a lymphocytic heart muscle inflammation: 1. Cancer. Excluded by the autopsy. 2. A bacterial or viral inflammation. Also excluded by the autopsy. 3. Toxic substances. The contamination of flight crews on board is known (both on trouble-free flights as well as so called “Fume Events”.) This is the likely cause for the lymphocytic heart muscle inflammation. In view of the fact that this is the third case in which a lymphocytic heart muscle was found and all three crew members died this is a very serious matter.’ Adapted from- Source: https://www.aerotoxic.org/cannon-law-press-release-15th-july-2015/ A serious matter indeed. However not serious enough for our Government to take action to prevent this from happening again. Contamination of cabin and cockpit air is a very serious and important issue for everyone - those who work onboard the aircraft and of course those who travel as passengers on the aircraft. My thoughts are with Warren’s family.
