# Quiet Skies **Domain:** Austin Research / Surveillance **Doc Type:** Research entity **Source basis:** Supplied essay and the specifically identified records; verification scope is recorded in [[wiki/Austin Surveillance Evidence Ledger|the evidence ledger]]. **Quiet Skies** was the TSA aviation-surveillance program examined in the September 30, 2025 Senate Homeland Security and Governmental Affairs Committee hearing. Senior Federal Air Marshal **Mark Crowder** appeared as a witness. The supplied essay also follows the program’s 2018 exposure through air-marshal disclosures and reporting. The program’s importance to the Austin argument is a documented category of surveillance selection upstream of arrival: people who were not criminal suspects or terrorist-watchlist entries could be selected for additional physical observation through risk and association rules. The essay records the 2018 scale, behavioral collection, and later restrictions; those historical details retain their individual reporting provenance. Crowder’s account of his wife’s selection through a shared itinerary belongs to witness testimony. The congressional record is the place to distinguish that account, agency responses, and committee conclusions. A hearing title’s political framing is not a finding about each person discussed. The mechanism connects to [[wiki/Computational Addressability|computational addressability]] because an identifier or association can alter how a system treats an individual. It is an upstream federal case in the Austin field, not evidence that the named traveler was assigned to a UT research program. The relevant comparison is selection and consequence, with each operational instance tied to its own record. ## Connected entries [[wiki/Secure Flight|Secure Flight]] · [[wiki/Watchlist Encounter Process|Watchlist Encounter Process]] · [[wiki/Fusion Center Oversight|Fusion Center Oversight]] · [[wiki/Information Asymmetry|Information Asymmetry]] · [[wiki/Austin Surveillance Field|Austin Surveillance Field]] ## Sources and corpus context - [[research/The Austin Surveillance Field|The Austin Surveillance Field]] - [Senate HSGAC — Quiet Skies hearing, September 30, 2025](https://www.hsgac.senate.gov/hearings/examining-the-weaponization-of-the-quiet-skies-program/) - [Congress.gov — Quiet Skies hearing transcript, S.
