OK, I gotcha'.
What I meant was that the 777 pioneered the big change in ETOPS because it was the only aircraft specifically designed for long distance flights and so when introduced, it was the one used to generate the data and have the rules altered because it was the only one. Now that the rules have been changed, other twin engine aircraft have joined it in long- distance travel when an emergency landing is not possible, including the A 350 you mentioned.
ETOPS is an acronym and it stands for Engines Turn Or Passengers Swim. Or something like that.
And I had to look up 'Panto time'.

Can I be more specific (it was late last night)
I was specifically correcting this section
"because it is the only large, long distance aircraft with two engines in the first place. "
Panto time
Oh no it isn't
