I may well present three scenarios in this thread; it, sort of, depends on the responses. In each scenario there is a hypothetical space craft, travelling at c and an astronaut on the craft with a flashlight which he shines from the back of the craft towards the front. There will also be one or two remote observers, with hypothetical instruments that can be turned on and off very quickly.

(1) The astronaut turns on his flashlight. In his RF the light travels at c to the front of the craft.

Observer A makes her observation as the astronaut turns on his flashlight. She sees no light.
There never was nothing.
