Narrative

DURING A LENGTHY GATE HOLD WITHOUT AIR CONDITIONING; WHERE THE PAX WERE ALLOWED TO BOARD; THE CABIN DOOR WAS SHUT AND THE PLANE PUSHED BACK FROM GATE. DUE TO INOP APU; ENGS COULDN'T BE STARTED AND NO AIR CONDITIONING WAS AVAILABLE. HELD ON RAMP FOR 1 HR BEFORE DOOR WAS FINALLY OPENED. CABIN TEMP HAD CLBED TO +90 DEGS F. I WAS IN THE PROCESS OF ADMINISTERING OXYGEN TO PAX WHO HAD DIFFICULTY IN BREATHING WHEN COACH PAX ATTEMPTED TO OPEN DOOR EXIT. HANDLE WAS ROTATED BUT DOOR DID NOT OPEN AND SLIDE THEREFORE DID NOT DEPLOY. AFTER AGENT FINALLY OPENED DOOR; PAX RUSHED OFF PLANE DUE TO HEAT. PAX WHO ATTEMPTED TO OPEN DOOR WAS REMOVED FROM FLT. PAX WHO WAS BELLIGERENT WHEN ASKED TO GET OFF ACFT AFTER ARGUING WITH DEPLANING PAX AND WHO GRABBED INTERPHONE OUT OF MY HAND AND STARTED SHOUTING ORDERS TO #2 FLT ATTENDANT TO TEND TO HIS BABY IN THE BACK OF PLANE; WAS REMOVED FROM FLT AS WELL. THE FACT THAT THE ACFT WAS BOARDED WITH INOP APU AND PAX HAD TO SIT ON ACFT WITHOUT AIR CONDITIONING ADDED; IF NOT CAUSED; THE PAX MISCONDUCT AND ANXIETY THAT THEY FELT; AND WAS A DIRECT CAUSE OF THE PAX NEEDING OXYGEN. DUE TO THE IN-DEPTH TRAINING AT MY AIRLINE; MYSELF AND MY CREW WERE ABLE TO EFFECTIVELY HANDLE THE SIT AND KEEP THE SIT CALM IN LIGHT OF PAX ANXIETIES.
