Devil aerodynamic brake and tail cone

One of or Captain used to land wit very high pitch,much more than the 12° limit in our books. Once after grounding we had alarm "TAIL CONE". Memory item was to verify if we lost the tail cone. The Captain answerd :"No matter, it is a false alarm". I said him again "TAIL CONE" and "we have to verify the tail cone who perhaps is on the RWY". He still was sure it was a false alarm , but as I insisted he called the Chief of the Cabin Crew to verify we still had the tail cone, sure it would be a false alarm. He called the TWR to inform them we were staying on the Runway to verify the false alarm. When the stewardess came back she was laughing and said "we are in a decapotable ".
At low speed and high pitch our MD-82 conic shaped tail-cone failed. The new beaver shaped tail-cone of our MD-83s staid connected by a forward depression/lift in the same situation. A truck searched the tail-cone (big and heavy !) in the gras beside the runway where the tail-cone had been rolling. The Tower did not see the tail-cone going away hiden by the fuselage...
Our plane manual said a tail strike risk exist on landing with more than 12° pitch In fact it was the emergency escape removable tail cone (pulling a handle pulling a connection wire) who was going away.
