The Zeppelins can land anywhere there's enough flat ground. And obviously the Home Chain radar system would be given a working over. Or alternatively, have German special ops teams under Skorzeny conduct a Daring Commando Raid on the radar installations by using Fa 223s to fly in and out. With the radars out of commission, the Brits will have to use the Mark One Eyeball to spot the attack. If the zeppelins come in at night once the radars are blinded, they might well have landed an entire division before the British realize they've been invaded.
And as far as generalized AA is concerned, that's why you'd have a jet-propelled variant of the Hs 129 available to do Wild Weasel duties. And then join the Fl 282s in turning British tanks into scrap before they reach the landing zones, or course.
You're a very bad sandman.
