There were also trials of C-130 landing and taking off on the USS Forrestal. No wire, no catapult.

Yeah, but they have long wings. 

Rumour had it that PR19s may have done the same................

The USMC operated Stinson OY Sentinels in WWII...

...and my grandfather told me about a USMC unit training with them when he served on the USS Ranger (CVA-61) between 1957-60. I probably have pictures of it in his old cruise books that I have. He said that the deck crew had to lean on the struts to keep them from lifting off vertically when the carrier turned into the wind because the Sentinel's take off speed was so low.
