What's the reality behind the hype on those other

technologies? I think the view is that, yes, hydrogen and electric-powered aircraft can potentially play a role, but it's just going to take longer, particularly with hydrogen-powered aircraft.

Most of the major players are now saying that's probably...

in terms of a narrow body type aircraft not going to be entering to service till beyond 2050.

You might see some commuter or regional aircraft before that but they're going to be pretty small less than 100 seats less than a thousand nautical miles in range.

I think the big change that we've seen in the last five years is real convergence of view around the importance that SAF is going to play and this is both at an industry level and a government level So in any scenario, SAF is going to be the primary mechanism for our industry to reduce our carbon emissions.

There are different types of SAF.
