In a post earlier this evening Aviation Week reporter Guy Norris confirmed information that I posted on Sunday. Namely that Boeing is targeting to return to certification flight testing by late this week (January 14th). Guy also confirmed that ZA002 will be flying again later this week (on the 13th instead of the 11th which I earlier reported. ZA003 and ZA006 will also be returning to flight within the next one week and it is widely expected that Boeing will announce the revised delivery schedule sometime next week.
ZA001 and ZA005 both have been flying test flights today but ZA004 has not flown. You can read Guy posting:
