Sparkchaser
An important detail from the article:
Johan Helberg told Norwegian broadcaster NRK that heâd slept through the whole thing and only woke up when a neighbor started ringing his doorbell.
Although as per some other news sources, he woke up only after his neighbor called him on the phone since he didnât answer the doorbell.
In any case, thatâs a relatively minor detail and now itâs a âletâs partyâ moment; plus now he has a great story to tell to others!
Airplanes have various proximity and collision avoidance systems, so maybe ships should have some of that technology, too, although it probably canât help much in âpower-lossâ scenarios,
