Whay would happen if an aircraft, suddenly, to enroll in a vacuum?

engines shut down, power shuts down. emergency miniature windmill extends provide backup power. no air power windmill, no backup power. power lost. hull pressurization shuts down. inside of hull adapts pressure outside hull (decompression vacuum). aircraft engages in free fall.

except depressurization inside aircraft, happen within first 2 seconds. is, assuming aircraft doesn't explode due pressure change (the hull exerts force inward, assisted outside pressure. if pressure outside drops, pressure on inside overpowers forces keeping few milliseconds. if hull can't adapt enough, explode).
