That was good. Spaced on a few that I should have gotten and flat out couldn't figure out the ______ Golightly. Knew it started w/ H but also knew there isn't a Heidi Tree out there anywhere.
Not sure what you were seeing when you looked it up, but it is definitely a tree with nuts that look like chestnuts. Don't eat the nuts, though, unless you're a deer. They are poisonous to humans.
I recommend changing this to aircraft with the widest wingspan. "Largest aircraft" has no single definition. The Spruce Goose is definitely not the largest by length, weight, or lift capacity.
