PM,
1. The captain. Although the SCCM may be part of the cause of the injuries. All orders given by any member of the crew are given using the captains authority.
2. There was no smoke. There was a strong smell of burning which became apparent after arrival on stand and after disembarkation had begun.
3. The captain.
4. Yes, having received an unsatisfactory response from the flight deck what would you like her to do? Wait? For how long? Saudia 163 ring any bells with you?
these sorts of people are a serious threat to the lives of passengers.
I think four people were injured getting out. How many people would have been injured or worse had she not ordered an evacuation?
