Stuff nobody seems to know about Lightning....

How do you clear a stuck In-Flight payment which failed 1002 days ago?

Seriously? I'm working on some new code for my node and both the LND nodes I have have stuck payments like this. Obviously this node has been rebooted and upgraded numerous times in the last 1002 days!
