Press Release – Immediate release
Boeing 787 Dreamliner First Flight – 15th December 2009.
Today marks a serious milestone in aviation history with the long-awaited first flight of the Boeing 787 Dreamliner. Few people, even experts, will be aware of the significance of a technical step change as Boeing actively down play the real reason.
In the late 1950s, the Boeing 707 used mechanical pumps (‘turbo compressors’) to bring fresh outside air into the passenger cabin. This system was safe and could not cause cabin air contamination.
In an effort to simplify operation and reduce costs, in 1963 the Boeing 727 was designed to use ‘bleed air’ – compressed air from the jet engines; this was despite concerns at the time that toxic oil fumes could contaminate the passenger cabin air – as was admitted by Boeing to the UK House of Lords in 2007. All jets aircraft and turboprops have used bleed air since 1963.
In 1999 the term Aerotoxic Syndrome was introduced by three renowned international scientists to describe the serious chronic ill health that arises from repeatedly breathing oil fumes in the confined space of an airliner cabin.
The Boeing 787 has returned to supplying fresh cabin air from outside, this time using electrically-driven pumps. Boeing has decided not to make a big deal about the inconvenient bleed air issue but concentrate instead on other ‘easier to understand and less contentious changes’ including lighter composite airframe parts which should mean reduced weight and therefore better fuel economy but admit to a ‘more comfortable passenger experience’.
The Boeing aircraft company should be congratulated on this brave, ‘ground-breaking’ decision to utilise bleed-free technology, but they should also have the confidence to admit their considerable commercial advantage over other manufacturers who have yet to understand the real cause of aircrew and passenger ill health, better known as Aerotoxic Syndrome.
This technical change may explain the record 850 orders for the unique Boeing 787 Dreamliner.
1963 – 2009 46 years of contaminated cabin air.
