From pics and models I've seen, the deck has just had the 16 B-25's on
deck with the Hornet's planes in the hangars.
While reading "The Doolittle Raid" by Carroll V. Glines, there is a pic showing two planes, possibly SBD's on the starbord side about two B-25's up from the stern. The caption states that the pic was taken as it was leaving SF Bay.
First I've heard of anything else other than B-25's on the deck. Have we been doing it wrong all these years?
