Some interesting comments. By accident I found a thread with a similar name.
My colleague and myself called this "coffin class" my accident not knowing this.
Memsab has flown to India this morning also on coffin class. I will be interested to hear her comments. I know she likes the privacy and not being bothered by "chatters" so she might prefer it.

His English was very clear.
He didn't hit anything as far as I'm aware.
Still prefer to hear a UK, US, A/NZ voice from the skipper of a aluminium tube though and that's speaking as a pilot myself.
