Whirlwind wheelbags
I've just finished a piccy of a yellow 22 Sqn Whirlwind for an ageing chopper pilot who tells me that when used on royal flight duties they could be fitted with flotation bags on the wheel hubs, as were the later RF Wessex. Safety police did not like the Sax-Coburg-Gothas flying in single-engine helos, hence rapid introduction of Wessex.
