Melissa Dray


Melissa Dray is a former Cabin Crew member from Perth Western Australia.


Melissa was 24 years old and had been flying for only 3.5 years when she was involved in a large fume incident in April of 1999 on a BAe146 aircraft. She suffered immediate side effects and was taken to hospital off the flight. Subsequent investigations of the aircraft found it had experienced a major engine oil leak. Her health deteriorated over the weeks and months following this incident and by September of 1999 she had crewed her last flight.


In conjunction with trying to get well, Melissa ended up pursuing a 20 year legal battle at times representing herself against her employer and then the aircraft manufacturer British Aerospace.


Melissa has spoken at major conferences about her journey and is featured in several documentary films.

Judy was an Ansett Australia Flight Attendant, flying the BAe-146 aircraft in Australia since 1984. She became incapacitated 6-8 November 1997, while flying 3 days on a British Aerospace BAe-146 aircraft during flights to and from Alice Springs. She was being exposed to fumes, (toxic vapours) through the cabin air, become totally incapacitated, semi-paralysed and barely able to speak, during flights to and from Alice Springs.


The aircraft maintenance report stated, “Number 2 bleed inlet duct and both sleeves on air cycle machine replaced. Duct cracked and leaking hoses”.


 Judy and then National Jet First Officer, Susan Michaelis, raised safety concerns and health problems with the Australian Government that led to the year long 1999 / 2000 Senate Transport References Committee investigation into contaminated air on aircraft. 


In August 2002, Judy settled with Ansett’s Insurer, nearly 6 years after becoming ill and suffering injuries that ended her career through no fault of her own.


Judy then retrained as a lawyer, graduating the same day as her son.
