New tag suggestion: stratospheric flight

For those pictures where the roundness of the planet or the border of the atmosphere to the darkness of space is visible.

See post #1524669 and post #223028

Why not simply stratosphere? We can tag flying where it applies separately.

Perhaps a tag referring to the curvature of the earth's horizon itself would be more direct.

I don't think pictures like this would look much different from ones from orbit, so how about we rename the orbit tag to something more general and use it for this? Maybe 'sky_high', which would require moving the present sky_high tag to 'sky_high_(tiger_&_bunny)'.

sky_high seems terribly vague...

i'm unaware we have orbit, but horizon earth and horizon space seem to give what was desired too.

space earth would also give plenty but varied result.
