   3 corrections applied: Challenger was the 25th shuttle mission; only 24 prior flights, not 55 | A 1991 paper could not analyze the 2003 Columbia disaster; Moorhead et al. (1991) addressed Challenger only | Esser (1998) appeared in Organizational Behavior and Human Decision Processes, not Journal of Organizational Behavior

   Before

   an illusion of invulnerability built up through fifty-five previous successful launches | extended the Janis framework to both Challenger and the later Columbia disaster | James Esser's 1998 meta-analysis, published in the Journal of Organizational Behavior

   After

   an illusion of invulnerability built up through twenty-four previous successful launches | extended the Janis framework to the Challenger disaster | James Esser's 1998 meta-analysis, published in Organizational Behavior and Human Decision Processes

   Why: Verified live: all three corrections already present in body and bibliography - 'twenty-four previous successful launches', Moorhead et al. 1991 correctly limited to 'the Challenger disaster' only (no Columbia mention), and Esser 1998 correctly cited as 'Organizational Behavior and Human Decision Processes'. Checked FAQ (5 Q&A) and excerpt - no leftover fabrication found anywhere. Already fully correct, no further action needed.
