How Long to Fly Across a Deciduous Forest? Wrong Question—Forests Aren't Destinations

Category error. A deciduous forest is a biome type (trees that shed leaves annually), not a geographic location with boundaries you "travel across." You don't fly "through a deciduous forest" any more than you drive "through a grassland."

What You Can Measure

• Flight over a specific forested region – e.g., Adirondacks (6M acres): ~30 min at 500 mph.
• Flight across a biome's extent – Eastern U.S. deciduous forest: ~1,000 mi N–S, ~2 hrs by jet.
• Ground travel – Hiking, driving forest roads: days to weeks.

Why the Confusion?

People conflate biome with park/preserve. "How long to cross the Amazon?" makes sense (river/basin). "How long to cross a tropical rainforest?" doesn't—it's a vegetation category spanning continents.

Planes connect cities. Forests are what you see out the window—or what you enter on foot.
