I wonder whether Archie had enough flexibility in the elbow and wrist to 
compensate for this? 
Could it not have utilised a flight stroke more like that of modern bats, with 
a lot of flexibility in the 
various wing joints, rather than having the more stiffened wing structure seen 
in modern birds?
