heading of an airplane in animate-point-along-route in examples

Hello,
The heading of an airplane doesn't look nice in animate-point-along-route of examples. It would be better if it's along the locus:

I'm looking for this too.
I'm also wondering why the line appear to be curved for this far distance, so orient the plane along the curve like this would involve bearing calculation, no ?

Hi @mourner, how about this?

That's right see the updated example in #6554. The line is curved as it represents the shortest line between two points in a sphere.
