The 90th entered service in early 1918 using the Sopwith 1 1/2
Strutters. These were supplemented by a few Br14s and a single SPAD
XVI until replaced by the Salmson 2A2 in August 1918
Tumbling dice 'coming up seven' were originally the personal insignia
of Capt William Schauffler while at the 1st Aero Sqn, and after
transfer to the 90th and three months active service, they were
adopted as the 90th official marking.
The 90th was one of the units that did not use stripes on the wings
of their aircraft. Flights were denoted by different colours of
their flight numbers. 'A' Flight used white with a dark border (1-6),
'B' Flight used yellow with a black border (7-12) and 'C' Flight
used red with a possibly white border (13-18). Going by this, it
would appear that my original (1991) depiction of a/c 12 was in
error and it has been updated.
