I didn’t know the hyperspace thing was from ROTJ, the first I heard of it was from the TPM rough draft:

Yeah, the first I heard of it was when I read Secret History and it mentioned the TPM draft where Anakin did it. The ROTJ one is much more reminiscent of what showed up in TFA however, insofar as it’s Han in both (not using the Force), with a similar set up (sneaking through the shield around a planet as part of the plan to blow up the Death Star type thing).
