Lockheed SR-71 Blackbird
The Lockheed SR-71 Blackbird is a long-range, high-altitude reconnaissance aircraft developed for the United States Air Force during the Cold War.
Also known as: SR-71, Blackbird aircraft
How big is it?
32.7 m long
Also 107.3 ft
Overall length · specified
Typical recorded range: 32.6 m to 32.8 m.

A little perspective
About the same scale as Rosetta spacecraft.
Rosetta spacecraft: Rosetta was an ESA spacecraft launched to study comet 67P/Churyumov–Gerasimenko, carrying the Philae lander and powered by solar arrays.

Rosetta spacecraft
ESA’s Rosetta spacecraft spanned approximately 32 m across its two deployed solar-array wings and had a launch mass near 3,000 kg. The Philae lander is included in launch mass, not shown as a separate body.
The marked deployed solar-array span is calibrated. Unmeasured illustration details are representative.

Why this measurement?
Why we use 32.7 m
For comparison, this page uses overall length. The record labels this value specified, so the stated convention rather than an inferred average controls the comparison. The recorded range is 32.6 m to 32.8 m.
