Smoke from the attack then made results harder to distinguish. It reports twenty-nine aircraft delivering the attack, separately from the larger force assembled for the operation. YT-T06

A small entry in a flying log
The RAF Museum reproduces a detail of Wing Commander Tait’s logbook identifying the Tirpitz operation at Tromsø and recording the ship sunk. This is a participant’s contemporary record of the operation’s outcome. The published crop does not establish which aircraft’s bomb caused which damage. YT-T20
The later naval technical investigation asks the separate question of how Tirpitz capsized, drawing on reports and information of uneven completeness. YT-T02
