Scooter Boy, it would be interesting to get your thoughts on the NTSB report - about post 26 in this thread.
My thoughts are that the TCAD may have been the cause of the acceident.
I read your posting when you made it, and wondered what the relevance was, and what point you were trying to make. Now I know, but I can't say I agree! I can't see where you draw that conclusion! After all the the NTSB says it was inadequate look out.
The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot's inadequate visual lookout during cruise, and the pilot of the other airplane's inadequate visual lookout during climb.
The TCAD seems to have given some warning..obviously not enough, but I can't say that there is anything in the report to say that it actually contributed to the accident!
