He was in panic, don't say he was RUDE.  DONT BE FUCKING INGNORANT.  How would you feel, trapped.  There is a reason he didn't just walk down the stairs...  They could of been taken out, or standing up could of killed him from no oxygen.  He was trapped, and was only looking for some help.  Yes they were doing they best they could to get it to him, but sadly it was not quick enough.  Many men died trying to save people as well...  They are true heros.
