Once communications with the Covenant were enabled, chief terraformist Katherine Daniels convinced pilot Tennessee Faris to prepare the WY-37B for use as a makeshift extraction craft, using her intimate knowledge of terraforming equipment to accurately rate the craft for the manoeuvres required. The Covenant was redirected to a remote planet after intercepting a mysterious signal shortly after, the ship's lander was destroyed and the expedition team sent to the planet were stranded.
CARGOLIFTER MAC REGISTRATION
One WY-37B cargo lifter, registration 33625381-1, designation LT-03, was assigned to the Weyland-Yutani colonization vessel USCSS Covenant as of 2104. Katherine Daniels operating the remote crane The lifter's controls were haptic and intuitive, lacking over-reliance on sophisticated electronics and thus requiring little experience to operate effectively and little effort to repair.

The sled's thrusters could be fuelled with a plasma intermix to increase engine output and push the lift far beyond the limits of its intended use. The key principle of the WY-37B's design was reliability and durability-the craft was built to endure tremendous damage and operate in extreme conditions ranging from sub-arctic cold to flying lava, and its modular design meant that stripping the sled of extraneous components-such as backup equipment and storage modules-made it lighter and faster. Behind the crane were the high-output rear thrusters, and complimenting these were four overpowered VTOL thrusters installed in pairs to port and starboard. Deploying the crane while the lifter was in motion ran the risk of causing the craft to destabilize and crash. Situated to the rear of the deck was a remote-operated crane arm that was docked flush against the hull this could be fitted with various tools such as a magnetic coupler, excavation claw, or a hook and cable. Personnel leaving the cabin to perform emergency cargo balance adjustments while the sled was moving could use a harness and winch to stay attached to the craft. Located under the deck, the lifter's undercarriage was equipped with retractable landing skis. At the front of the craft was a retractable loading ramp, along with a pressurized crew cabin.

Running along either side of the deck, curb rails and latching points were fitted to port and starboard. The platform's metal deck was fitted with clamp-down hardpoints and could be magnetized, and featured non-slip treads. It was constructed around a large platform that could be used to move heavy equipment, cargo, and materials such as housing modules from a vessel in low orbit to a planetary surface. The WY-37B cargo lifter sled was built by Weyland-Yutani Corporation as an item of orbital to ground colonization lift equipment. " Anybody and anything can fly a cargo lift-as long as it's straight down." ― Tennessee Faris (from Alien: Covenant novelization)
