As with any such major book this one has its few gaffs.

• Marc Ouellet notes that WO Boutin is mis-named on pages 264-265 as WO Boivin. Apologies to WO Boutin.
• Vic Johnson points out that Lahr is not in Bavaria, as erroneously noted; and that Canadian units did not fight at Verdun (p.148).
• Marshall of the RAF Trenchard is mis-identified in photos on p. 9 and 29 as Tedder.
• The Sabre 2 on p. 10 is called a Sabre 5.
• As noted above, LAC Curran was promoted by CANAV to be an F/O.
