This view of the Whitley I K7211 shows the wide chord wings to advantage. This Whitley became one of the three prototype Whitley IVs and was re-engined with Rolls-Royce Merlins. K7211 flew with Nos 58 and 10 Sqns before being lost in the English Channel on January 23, 1939.

Whitley I K7191, from the initial production batch, served with Nos 10 and 166 Sqns.

Whitley I K7209 later became one of three Whitley IV prototypes. Early Whitleys were delivered minus nose and tail turrets, though most aircraft received these rather necessary items at a later date.
