Allan McDonald, in charge of the booster rocket redesign task force, told members of Congress that the new booster joints would fall into the "criticality-1R" category, meaning that they would have a backup. No specific design had yet been chosen, and the engineer stated, "We're looking at some designs with o-rings and some without. We're looking at various seating concepts." McDonald was taken off Morton Thiokol's solid rocket team after testifying before the Rogers Commission concerning his objection to launching the Challenger in cold weather, but was reassigned to head the task force after complaints from Congress.
