The Altitude Project

8662 is an interactive sound installation commemorating the life of the celebrated English female pilot Amy Johnson who, at the time of conferring memorial parks on other historic aviators in Katoomba was overlooked.

The work was commissioned by Miriam Williamson and Mahalya Middlemist for the Blue Mountains Altitude Project and will be installed in the Kingsford Smith Park, Katoomba from 5 to 9pm on Saturday the 17th of February and Melrose Park, Katoomba on Sunday the 18th (time to be advised as these are one day only events).



The sound installation celebrates Amy’s life in the soundtracks composed from original music and sound design and archival recordings of Amy, including her talking about her England to Australia solo flight from the 5th to the 28th of May 1930. Two old time songs written and recorded about Amy and performed by Jack Lumsdaine and Bob Molyneux in 1930 titled “Johnnie, Our Aeroplane Girl” and “Just Plain Johnnie” have also inspired the tempo and melody of the work. 

The soundtracks are mounted on stands and placed into the ground standing upright in four separate locations along the embankment as you walk down the hill into the Kingsford Smith park from the south side. Passers by can trigger the individual soundtracks as they move within close proximity to each of the 8662 stands and have the option of listening to the work through outdoor speakers or headphones available on one of the stands. The title of the work comes from Amy Johnson’s Aviator’s certificate, No. 8662.
