Phase 2: Technical Expansion (The "Transcriber's Notes")
Glossary of Terms:
* Appendix "A": The standard annex to a Royal Air Force (R.A.F.) or South African Air Force (S.A.A.F.) Operational Order, providing the specific disposition of aircrews and airframes for a given mission.
* 1st. / 2nd. Sub Flight: Tactical subdivisions within the 21 Squadron formation, typically consisting of three aircraft flying in a "vic" or "V" pattern to maximize defensive fields of fire and concentrated bombing accuracy.
* Machine No.: The individual aircraft identification, consisting of the squadron identification letter and the R.A.F. serial number (e.g., "A" 1669).
* Maj. / Capt. / Lt. / 2/Lt.: Major, Captain, Lieutenant, and Second Lieutenant; the commissioned officer ranks of the S.A.A.F. personnel listed.

Operational Context:
The personnel and machines listed on this sheet were tasked with high-level bombing operations against Martuba West and Derna on 16 November 1941. This date is critical as it represents the final 48 hours before the launch of Operation Crusader, the Allied offensive to relieve Tobruk. The strategic focus was the neutralization of Axis airfields to secure air superiority for the Eighth Army's advance.
The aircraft listed are Martin Maryland Mk.II light bombers. The specific note at the bottom of the page indicates a tactical substitution: aircraft "Q" 1649 replaced "V" 1612 for the second operation of the day. This substitution, combined with the earlier report of electrical and propeller switch failure in another aircraft during the morning sortie, underscores the significant maintenance challenges faced by 21 Squadron while operating from forward landing grounds like 021 (L.G. 21). The presence of senior flight commanders, such as Major Stewart and Captain Thackwray, emphasizes the importance of these pre-offensive strikes despite the deteriorating weather conditions that eventually forced the formation to divert to Derna.
