I haven't yet seen the recovered shell of the FDR; so two possibilities for the storage media and data capsule:
- Data capsule intact with or without outer cover on -- being cylindrical it could be a long way downhill if not trapped in debris. Rainfall can move it a long ways and even bury it in sediment. In the mountains heavy rain and debris flows are ever present. Snowmelt also triggers debris flows. It may be necessary to vacuum dredge the streambed and run it through a screen. All this in difficult terrain.
- Capsule broken and storage media scattered -- the entire hillside area will have to be treated like an archaeological dig. Labor intensive, time consuming and distressing because of fragmentary human remains
