"Several changes were made to the design of the Apollo spacecraft to improve crew safety. The flammable oxygen environment for ground tests was replaced with a nitrogen-oxygen mix. Flammable items were removed. A new respect developed between the astronauts and the contractors concerning design changes, which were implemented more effectively." -- Elizabeth Howell, "Apollo 1: The Fatal Fire", Space.com, 2017-11-15
