a wing including a tip and extending in a wing spanwise direction defined by a leading edge of the wing, and
a wing tip device extending outwardly and upwardly from the tip, wherein the wing tip device includes:
a leading edge swept back from the wing spanwise direction by a first swept back angle;
a front spar extending outwardly and upwardly, wherein the front spar is swept back from the spanwise direction by a second swept back angle at least as great as the first swept back angle;
a rear spar extending outwardly and upwardly, wherein the rear spar is swept back from the spanwise direction by a third swept back angle less than the second swept back angle, and
a cross-brace spar linking the front spar to the rear spar and oblique to the front spar and the rear spar,
wherein the cross-brace spar extends upwardly from an inboard location proximate the rear spar to an outboard location proximate the front spar, and
wherein the cross-brace spar twists as the cross-brace spar extends upwardly.
