A restriction with no published ceiling was shown with one

The airspace and notice pages rendered TFR 6/1029 as Surface to 910 FL. The notice's own text reads SFC-UNL, and FL 910 is the FAA's sentinel value for unlimited. The site had put a literal 91,000-foot ceiling on a restriction the authority says has no ceiling at all.

Fixing it exposed a second fault in the same transform, affecting three more live notices. TFRs 6/0427, 6/0543 and 5/3679 each read SFC-5000FT AGL or SFC-2000FT AGL at the source and were rendered as Surface to 5,000 FT and Surface to 2,000 FT, dropping the datum. Above ground level and above mean sea level are different ceilings over terrain, and that distinction is the entire point of the field.

Four of the five live notices were wrong: one ceiling invented, three datums dropped. The transform now reads the value, the unit and the datum at both the floor and the ceiling, and carries an unrecognised unit through verbatim rather than guessing at it. Fourteen fixed test cases cover it, including the ones that caught a bug in the fix itself. The five live records were corrected and republished, and the result was re-measured on the delivered pages rather than assumed.

A restriction the FAA had withdrawn was still shown as live

TFR 6/1027 was dropped from the FAA's list and was correctly identified as retired by IGW's own sweep at 13:38 UTC. It was still in the delivered HTML of the airspace page at 17:40 UTC, three times over, rendered as a live restriction with a boundary, an altitude ceiling and an effective window.

The cause was one missing step. Retiring a notice takes two: drafting the staged record, and unpublishing the copy already live. The sweep did only the first, and a newer draft does not remove an already-published copy. The sweep now unpublishes the live copy first and drafts the staged one after, so no later publish can bring it back.

This is the worst class of error this site can make. It is not an awkward sentence or a stale figure. It is a notice the issuing authority had withdrawn, shown as though it still applied, over airspace people fly in. The live record was removed and the site republished before the fix was finished.

Date labels and Tiangong specifications corrected

Film and NASA archive dates could appear a day early in some time zones. Date labels now use UTC consistently; the source publication timestamps are unchanged.

Mission Control displayed 22,000 kg and 50 m³ against the Tiangong space station without verifying that those figures described the complete station. Those values have been suppressed and the page identifies the current station mass and volume as unverified. No replacement figures have been inferred.
