Early this morning before first light I smelled smoke and was immediately wide awake. I got up and stuck my head out of the hatch. All was clear. I reminded myself how sensitive the human nose is and went back to bed. I could not go back to sleep. John woke up and smelled smoke. I told him I had been out to check and all was clear. He went to check himself. All was still well, but John could not settle and went to sit in the Captain’s chair and read his I-pad. At which point with him worrying about it, I went straight to sleep.
