securing flight recorder
There are images of the flight data recorder located in the tail of the airbus that dragged its tail in Melbourne this year.
Surprisingly the recorder was completely dislodged by the impact of the tail hitting the ground.
Would a better solution be to have it secured into a beefy bit of airframe, noting that there are not always "big bits" remaining after a crash.
Also, perhaps it needs its own "Rescue Streamer"?
"Rescue streamer" is in use with the US Navy, when stored it is an inch in diameter and 4 inches long, but deployed and unrolled it becomes a 40ft long 4 inch wide hi vis streamer that floats on the surface or can be deployed on land.
Would half a dozen streamers made with a metallic layer attached to the recorder aid the search? Even if they disintegrate on impact they would leave a trial in the direction of the the recorder?
