First, I wonder if there may be a typo here in the name of a ship. To my knowledge, Dragon doesn't make a Saratoga in 1/700 scale. (Trumpeter does - but it's in prewar configuration and doesn't have a transparent flight deck.) To my knowledge the only WWII carriers in the Dragon line are the various ships of the Essex class, and a couple of Independence-class kits (which originated with Skywave). If there is a Dragon Saratoga out there - either the WWII one or the postwar, Forrestal-class ship - I'd be interested to see it. The Trumpeter kit is a fine one, but recent evidence suggests that Dragon would be likely to do even better.
I've got a Dragon 1/700 Hancock, and it does have a transparent flight deck. The kit also contains a flight deck molded in grey. The transparent one doesn't have all the detail - the tie-down strips, for instance, that the opaque one does. (Such details would make it hard to see through.) The clear flight deck offers the option of showing off whatever detail the modeler puts on the hangar deck
The aircraft also are molded in clear plastic. The idea here is that the modeler can paint all of the aircraft except the canopy. The manufacturer likes to put all the aircraft parts on one sprue, so the wings, landing gear, propellers, etc. get the clear plastic treatment too.
Same goes (sometimes) for small boats. I've got a Dragon Arizona. That ship carried some boats with canopies that had transparent ports in them. So Dragon molded all the boats in clear plastic.
I confess I have some mild reservations about whether that's the best way to deal with the problem of clear canopies and boat portholes, but lots of modelers seem to like that approach.
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
