I am now finding some of the posts on this subject interesting and useful.
Thank you BOAC for the explanation on tail pipe fires and maybe examples of this type can be used in CRM to help we the cabin crew understand the aircraft a little better.
We all never stop learning so maybe a little more interaction between flight and cabin crew at CRM will help those cabin crew who may need to, define 'catastrophic' from non catastrophic.
Many thanks,
