They have the raw data in 5 minutes from the box, I'll expect they will redact out anything that clearly spells out what really happened.
Pretty clear to me they hit fast...you would think Ground Prox would have been going crazy in the area, pilots either didn't have it working, turned it off, or didn't have the current database. A screw up either way.
Most demonstration flights are about performance 'look what it will do'...for all we know they were testing some performance limitation, screwed up...couldn't recover fast enough. Wouldn't surprise if the were testing the ground prox.
