I have four references to combat reports by a Lt/Capt R H Hood. The first two are for Lt R H Hood of 23 Sqn.
22 Aug 1916, 1830 Hours, an indecisive combat with a "Type F" (I have yet to track down a translation of the Type designations used by the British for German aircraft in the 1915-1916 period), W of Cambrai, in FE 2b 5213, with Sgt D Black as gunner. Reference: CR: 3Brig/30 [F52]
31 Aug 1916, 1015 hours, an enemy aircraft OOC (out of control), E of Bapaume, in FE 2b 6975 [the CR gives only 697], with Corp J Meakin as gunner. Reference: RFC51; CR: 3Brig/30 [F97]
The other two are for Capt R H Hood of 18 Sqn.
5 April 1917, 1200 hours, an Albatros D OOC, Inchy, in FE 2b A5464, with 2nd Lt
James Robert Smith as gunner. Reference: RFC82 (no names);
Above The War Fronts [I have not cataloged the actual CR yet -- hopefully I have it]
6 Spril 1917, 1000, an Albatros Scout forced to land and captured, between Croisilles & Ecoust St Mein, in FE 2b A5464, again with Smith as gunner. Reference: CR: 18Sqdn/1219-34 [F26] (in 5464)
I would assume that this/these R H Hood(s) are the same person, and are your Robert Hood Hood. This can be verified by checking his microfilmed card in Air 76, which will give some details of his life (usually date of birth, parents name and residence, possibly his residence at time of enlistment), and a fiarly good service history (units, dates, awards, medical events).
The reference to 3Brig/30 above is to Air 1/2245/209/42/30 1916 August; the reference to 18Sqdn/1219 is to Air 1/1219/204/5/2634/18 Sqdn, folio/frame 34. The [Fxx] refers to a sequence number of appendix F of the Brigade War Diary for the given month.
