There’s that photo of an AA missile that broke loose from a carrier landing, passing by a flight deck crewman or two.
He said Cherbourg (small peninsular mass extending into the E. Chanel) was surrounded and cut off. The allies didn't want to back track for it ... so they just bypassed it.
After bombing runs, some Crews returning to bases in S. England had stuff hung-up in the bomb bay or had unused stuff, they'd try to jettison it flying over Cherbourg or in the Chanel, rather than risk landing with it on borad.
