What specifically do you think would happen If you flew into the sun in a fireproof suit?
One-alarm, two-alarm, three-alarm fires, or higher, are categories of fires indicating the level of response by local authorities, with an elevated number of alarms indicating increased commitment of resources. The term multiple-alarm is a quick way of indicating that a fire was severe and difficult to contain. This system of classification is common in the USA among both fire departments and news agencies.
Having been a sailer for 40 years this is a question I've often considered. The problem is I've never been given a good answer. I can tell you sailboats are hit by lighting more often than you would think, yet the numbers of fatalities is very low. There's one theory that the rigging, all the wires, actually act as a protective cone. But I've no proof it's true. On a more practical vein, lower all sails, put the anchor out and go below. Don't stay near the electronics or sit atop the engine. Good Luck!
