In the early 1960s, deployment of rocket-powered ejection seats designed for use at supersonic speeds began in such planes as the Convair F-106 Delta Dart. Six pilots have ejected at speeds exceeding 700 knots (1,300 km/h; 810 mph).
I calculate about four days. The slow solar wind which is the bulk of it, travels at about 400 km/s. The sun is about 149,000,000 km from earth, which works out to about 104â¦ hours. A coronal mass ejection, a massive burst of solar wind with consequences for radio and satellites, may reach earth 1-5 days after eruption.
