Abstract
This article explores efforts that are being put into developing a business jet called AS2 and various challenges in developing the same. Aerion’s 12-seat tri-engine AS2, unveiled in spring 2014, is designed to have a range up to 5000 nautical miles; reach 51,000 feet; and cruise at speeds between Mach 1.2 and Mach 1.6. About the time it is ready to fly commercially, possibly as early as 2023, the market could support annual sales of 30 supersonic business jets. NASA and Lockheed Martin have been exploring a variety of options for quieting sonic booms. In its Strategic Implementation Plan, released in 2015, NASA states that ‘the viability of commercial supersonic service depends on permissible supersonic flight over land.’ It is however noted that the success of the next generation of supersonic transport will ultimately come down to economics. Prospective buyers of supersonic business jets will include corporations and ultra-high net worth individuals.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
