Well the SAS wouldn't have to be parachuted into enemy territory, they could have been sent in by boat to the Dutch or Danish coast dressed in civilan clothes or German uniforms and make their way to the target zone as seperate units and then infultrate the local populis or garrison. Then after some time infultrate the target, sent charges, and exfultrate and then make their way to the coast to be picked up. Yeah I do realize it sound far fetched but who knows it could have worked, not a bad idea for a book though .
