I did Denham-Land's End (St Just) & return, all in one day, in a Rallye, 40 kt easterly @ 2,000'. Took 7 1/2 hrs! all in one day. A few fuel stops along the way back. Numb bum at the finish, then off to a night shift! Ah, the folly of youth...
Seemed to have satisfied the CAA. Kept the landing fee reciepts for a while, was never asked for them.
Cheers,
