It is interesting that Canadian airborne or paratroopers' wings appear to be an anomaly among Canadian military insignia in that unlike glider pilots' wings or RCAF/RCN pilots' wings and other army insignia such as trade badges, marksmanship badges, and certain badges of rank, they are devoid of a crown, the symbol of monarchy. Was this due to American influence? Apparently Canadian jump wings did not exist at the time that the initial batch of Canadian jumpers were trained in the US.
On the other hand, British parachutist wings, unlike the cap badge of the Parachute Regiment, also are without a crown, but could that have been in part due to the condescending RAF attitude that relegated British jump wings to a location on the upper sleeve rather than above the left breast pocket? Interestingly, the RAF jump instructors' wings are worn on the lower sleeve in the manner of a trade badge. No wings at all for them and British jump instructors to this day, I believe, are from the RAF.
