A hearing has been held about a woman dying on a Southwest Airlines plane in April. There had been a loud bang and the cabin was full of smoke. As flight attendants went to check that passengers could get oxygen, one found a woman, still strapped in her seat belt, but with her head and arm hanging out of a broken window. Two male passengers helped to pull her back into the cabin, but Jennifer Riordan could not be revived. The loud bang was caused by engine failure but everyone else survived.
