I must now give credit to the website and message board at www.ArmyAirForces.com. It was here in 2008 that I first found Mattias searching for information about the Liberty Lady. This is a wonderful research resource. If you go to the “Research Help” page you will find many online places to look for information. Yesterday I downloaded the Enlistment Records of Herman and his two brothers. All three Allen boys were serving in World War II at the same time. 
There are thousands of posts from relatives of veterans who, like me, are searching for clues. Yesterday I read a message sequence where two sons of veterans who had served together found each other. The one wrote, “I’ve been searching for you for years!”
Yesterday I posted a question and within minutes “Mark” emailed me the Macr 2735 which he explained is a copy of the actual Missing Air Crew Report for the Liberty Lady crew. One interesting fact I’d never seen: a list of the “installed weapons” that were on the plane. There is also a notation “RTD” next to each of the ten crew members and Mark told me that means “Returned to Duty.” Which they all eventually did …
There is a store on ArmyAirForces.com and proceeds from this help support the website. I am ordering a mousepad with a picture of two B-17′s.
Thanks, Mark, for your help and thank you to all the veterans and friends of veterans who monitor this site!
