Three short multi-era fics

I pinched three spare prompts from thisbluespirit's last fic meme. Here are the results:
( Liz + Lucie, technical difficulties )

( Lucie + Eight + Clara, road trip )

( Adam Adamant + Clara Oswald, flying )

Oh, and if you've saved any Teaspoon links between 26 September and yesterday, they probably point to completely different fics now; Teaspoon had to be reverted to a backup, and though at least some people (such as me!) have re-uploaded their stories it won't have been in the same order as before.
