Mel Tisdale April 8, 2016 07:43 AM Imagine hitting a particularly energetic thermal or downdraft, or even the wingtip vortex from a 'heavy' or 'super'! Nik April 8, 2016 08:23 AM Why not make two wings so that both brace each other, ie, like a biplane wing, but with the tips connected, they could then be shorter. DomainRider April 8, 2016 11:30 AM Wow, half the fuel and emissions makes it a no-brainer, but they may have to redesign airport taxiing and handling facilities if the wingspan is 50% bigger... watersworm April 8, 2016 12:47 PM Half the consumption ??? Hope so, but i am a little sceptical. Waiting for real life results. Primecordial April 8, 2016 02:15 PM Where is the fuel going to be stored? Martin Hone April 8, 2016 04:21 PM These so-called trusses are generally known as 'struts'. Most small, high wing light aircraft (think Cessna) have a strut braced wing rather than having to have a much stronger and heavier cantilever design. So nothing new here. And a very high aspect ratio wing is generally used for high altitude work, as in the U2 spy plane as well as in gliders..... sagebrush6 April 9, 2016 12:41 PM An issue not addressed is airport parking. There already seems to be a shortage of parking on the tarmac now. Timelord April 9, 2016 03:01 PM Both NASA and Boing have been studying joined-wing aircraft for decades. Why are they stepping back from that in favor of this? Lance April 13, 2016 01:41 PM Sagebrush6, you are right, there are wingspan limits for aircraft terminals. They would need to fold the wings up to fit into them.
