Roadtrip,
Dear me. I intended to suggest that the remote controlled aspects of the program were successful, not the fuel crashworthiness aspects. I guess that I really must start using qualifications on top of qualifications in my posts.
You are quite correct in that the FAA sponsored NASA CID program was an incredibly underwhelming success in respect of the fuel additive idea. It put FAA proposals to mandate the stuff aside very rapidly. I have some video clips of the impact sequence tucked away somewhere in the office and they make for entertaining viewing.
My recollection of reports was that a number of subsidiary tests programs were successful. If my memory is up to it, there were a number of cabin crashworthiness tests involved which was my interest at the time.
