At the end of the day the whole RTO debate is irrelevant noise IMO, for whatever reason, the skipper wasn't happy, the call was 'Stop!', they successfully completed the procedure, end of story! The actual issue is who called for the emergency evac once they'd successfully returned to the bay, and why? Rumor has it that it was initiated by the cabin crew and/or pax, and the cockpit crew were unaware of what was happening until it was well underway!
Clearly the adrenaline levels would have been somewhat elevated all around after the RTO, but I think the CX spin doctors might have their work cut out for them when the CAD report is published.......
