So is everyone of the opinion that any hull breach or loss of control is going to result in a catastrophic event- not justifying donning the suits?

If there were the slimmest of possibilities of somehow riding a disabled shuttle to a survivable point of egress- why not suit up to ensure you're not incapacitated within a few seconds of the event? (The crew members didn't have time to lower and lock their visors)

Columbia was a special situation where there was suspected damage to wing. The priority of checklist items was somewhat left to the discretion of the Astronauts. With prior knowledge of the damage, wouldn't being in your seat as soon as possible with the suit pressurized be prudent?

There’s a fire hazard because of O2 buildup in the crew module when the suits are pressurized. I wonder what the risk assessment looked like when comparing the risk/consequences of fire to loss of consciousness/death due to depressurization?

(Why do they use O2 to pressurize the suits and not compressed air?)
