Abstract
The Lockheed Martin F-35 Lightning II is a three variant family of singleseat, single-engine, all-weather, stealth multirole fighter aircraft currently in production for multiple US armed services and partner countries. The F-35C is the carrier variant design of the three variant family. Drop testing of a full scale structurally complete aircraft is required for verifying compliance with the US Navy structural integrity and flight certification requirements for the F-35C carrier variant aircraft. The US Navy also requires a full scale drop test prior to clearing the aircraft to conduct high sink rate landings in flight test. The drop test program consisted of simulated shipboard landings for a variety of design touchdown conditions at specified aircraft attitudes, sink rates, and aircraft store configurations. The test objectives were to: (1) verify that structural integrity and functional design requirements for shipboard landing impacts have been met; and (2) collect loads and dynamics response data for correlation with analytical predictions. The F-35C drop test program successfully completed a total of 47 simulated shipboard landings without any structural failures and with good correlation between measured and predicted loads. The drop test results were used to clear the F-35C aircraft for shore-based carrier suitability flight testing and initial shipboard trials.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
