With the sun soon to rise in the Pacific, Solar Impulse 2 continues scooting at over 60 mph toward Honolulu as the third night comes to an end.\u00a0 Significantly, Andre\u2019 Borschberg and the 747-size plane have made it past the Midway Islands, once a stop-over for Pan-Am Boeing 314 \u201cChina Clippers.\u201d<\/a>\u00a0 Even with their 3,500-mile range, those luxurious planes needed a fueling stop mid-way between Hawaii and China or Guam.<\/p>\n

\"Boeing<\/a>

Boeing 314 “China Clipper” had 3,500-mile range, total luxury for passengers – but still had to make stopovers for refueling<\/p><\/div>\n

The islands were important enough as a way station in the vast Pacific that one of the largest and most decisive battles of World War II took place near them.\u00a0\u00a0 In a battle terrible destructive to both sides, U. S. forces sank four Japanese carriers, essentially casting the fate of the remaining battles.<\/p>\n

\"Midway<\/a>

Midway National Memorial commemorates WWII battle. Albatross next there, but are endangered by worldwide plastic pollution in oceans<\/p><\/div>\n

The still-important role of the islands as emergency landing sites was reinforced in 2014 with the safe arrival of a Boeing 777 f<\/a>ollowing \u201can odor\u201d and failure of radar and other electronic systems.<\/p>\n

The idea of a \u201cpoint of no return\u201d has been crucial in flight planning with fossil-fuel powered airplanes.\u00a0 The midway point of a trans-ocean flight is a psychological and physical reality, with options quickly fading as the aircraft passes that imaginary point in the sky.\u00a0 With a craft like the Solar Impulse, even marginally better batteries would negate the whole idea of crossing an imaginary line where turning back was impossible.\u00a0 Flight planning for this leg of the journey has to take into account the short nights and long days in the Northern Pacific.\u00a0 Trying this journey in the darker days of fall or winter would leave the current system wanting.\u00a0 Near-future improvements in batteries will allow flight of solar-powered aircraft through the longest nights.<\/p>\n

\"Seemingly<\/a>

Seemingly odd behavior of Solar Impulse turning its back to the sun is to speed battery recovery with favorable angle for solar cells<\/p><\/div>\n

We continue to applaud the brave and resourceful pilot and the superb intelligence behind this voyage.\u00a0 God speed!<\/p>\n
