Repainting them between flights is a real pain.

This wouldn't be a hull-loss or a major rebuild? I'd think the runway is keeping some of the aluminum from the nose for itself. Plus that's a lot of vibration near sensitive radome.

Not even close to a hull loss. Delta's Tech Ops will have this plane back in service very quickly.

So is this plane totalled? Or can it be repaired and returned to service?

It was already due for the knacker's yard as it is so old, so it definitely a write-off now.
