I starting working on finding info on Haynes as he seems to have had quite a career.
Here is an article from 1940, when he joined the RCAF. I will just post the link here to see if this is going to work. Let me know whether or not you can read the article. I believe there are limits to the number of actual jpgs a person can post and I have used up much of my allowance.

When flying with the 499th Haynes had major engine problems during a mission to Nagoya on 14 May 1945 and ended up bailing out with his crew back over Iwo Jima.

The MACR is quite detailed. For those with fold3 access it starts here:

Haynes was the last to bail out and 10 seconds after he left the ship the plane exploded. Haynes landed in the water off Iwo and was rescued. Of the 12 man crew, 5 landed on Iwo. The rest landed in the water and two of those were never found.
