Then I'd go with Australia.....and I don't want those black boxes to come to the USA since if either data cannot be extracted or there's an error made when doing so that destroys some of the data, this would be so much worse for Boeing and the FAA/NTSB. I trust them, but I don't want even the slightest risk of the investigation being viewed as rigged in any way.

OTOH, IMO it's almost criminal that the black boxes weren't immediately sent for analysis as soon as they were found. Plans for where to send them should have been arranged in advance instead of waiting for days (with those MAX 8s still flying around and/or being grounded) before even asking Germany.
