| About seven minutes after the cabin depressurization, the co-pilot visually confirmed the structural damage in the cabin. |
| However, after the depressurization, the ambient noise in the cabin made the public address system practically inaudible. |
| Its operation has led to the destruction of the frame and depressurization of the cabin, which had an explosive character. |

| We are sure that there is no depressurization in flight, because all the masks were still in the box. |
| And if it was, indeed, open, there would be a number of other problems, including depressurization. |
