John - While I agree with many of your points...
BOTH of the accidents you mentioned above we
- outside of competition
- by non competition pilots
- by pilots "emulating the big guys"
Points to training, not banning passes...
Thanks,
Best Regards, Dave

PS: Not a new problem. Discussed in my 1987 article:
