Do you mean dispersion as in "a pulse gets longer in time due to different length of paths taken by different photons due to scattering"? If not, what do you mean? My point about seeing a flash was precisely that SNR is high, beca

I don't really get why the range is this low. I can see flashes of light from a signal mirror from a place more than 10km away (and there were signal mirror links of ~100km in very good weather). In these systems, the noise should be w

Note that this was not a code patch: This was a sequence of changes to the program state that tricked it into ignoring the abort switch. The code itself was stored in read only core rope memory, so it was physically impossible to change it

All of the code was in read-only memory (core rope), so it was impossible to modify it. There was at least one case when the behaviour of the code was significantly changed in flight to work around a hardware failure (shorted button). This
