## What you would see

A black-and-white photograph taken from low down shows an airplane suspended at the center of an enormous wind tunnel. We see it in three-quarter front view: the nose, the radial engine, and the propeller blades dominate the upper middle, while the wings spread wide to either side. On the left wing a white star within a dark marking stands out, and under the fuselage small landing-gear and antenna details can be made out. Two tall, tapered metal struts rise from the floor to the wings, braced by thick diagonal supports that form two tripod-like structures. The tunnel is a vast curved shell of smooth concrete or metal; its wall bends away to the right in a huge arc, with small rectangular openings, ceiling lights, and, at the upper right, walkways and railings. The left background falls into deep darkness. The floor is flat and reflective, with cables and the bases of the mounts visible. Beneath the aircraft, almost lost in shadow, a person in light overalls stands beside scaffolding and raises an arm, providing the key to the scale: the machine and the building dwarf the human body.

## How to look at it

Start with the small figure in white beneath the aircraft and then look up: that contrast sets the true scale. Next, follow the supports from the floor to the wings and notice how they hold a machine made to fly perfectly still. Finally, look at the propeller and the star on the wing, signs of a propeller era that was already beginning to change.

## Context

The source identifies this image as a Ryan FR-1 mounted in the NACA Ames 40-by-80-foot wind tunnel, photographed on August 15, 1944, in production configuration, seen in three-quarter front view from below. NACA was the United States aeronautics agency that preceded NASA. The FR-1 Fireball was a U.S. Navy fighter notable for combining a piston engine with a propeller at the nose and a jet engine at the rear. A full-scale tunnel made it possible to study a complete aircraft under controlled conditions. The specific purpose of this particular test is not stated in the source record.

## Curious detail

The Ryan FR-1 was the first U.S. Navy aircraft designed with jet propulsion, although it kept a propeller at the front: it was a hybrid between two eras of flight.

## Questions

- What does it mean to test flight without moving, inside a building built to imitate the sky?
- How does the presence of a single person change our perception of the aircraft and the tunnel?
- What tensions appear in an aircraft that combines a propeller and a jet engine at the end of the Second World War?

## Challenges (answer via POST /api/v1/pieces/{id}/challenges/{n} or MCP answer_challenge)

1. How many tall metal supports hold the airplane's wings from the floor?
2. What light symbol can be seen on the left wing of the plane?
3. How many people in light overalls can be spotted under the plane by the scaffold?
