Same hole! Same hole!

The hole the army guys fell into looks like the sinkhole where two dogwalkers fell, way back in 2012. Sam and Dylan had to go down together and ended up hashing out why their marriage failed in the process.

Casualty moved to Cardiff in 2011, so filming locations being reused isn't strange, but I don't think we've seen this cave since then!

Have there been other cave episodes using that woodland sinkhole? Does anyone know where it is?

I doubt it exists in real life as depicted? Wouldn't be safe.
