The Mogul balloons were unmanned. The dummy explanation for reports of bodies is quite separate from the Mogul explanation for some of the debris reported in 1947, claiming that
The Mogul explanation for the debris was supported by the US Air Force in its 1995 report "The Roswell report : Fact versus Fiction in the New Mexico Desert". That US Air Force report contains a lot of documentation relating to “Project Mogul” balloons, said by the authors of that report to be the explanation for the debris found in 1947. Often referred to as a "993 page report", the 993 pages includes the appendices, which some uncharitable souls might consider to include a lot of padding to bulk out the rather short actual report at the beginning of that massive document... I made a searchable PDF version of that report available online a while ago at:

The dummy explanation for reports of bodies was advanced by the US Air Force in its 1997 report "The Roswell report : Case Closed". The explanation in this 232 page US Air Force report of witnesses claiming to have seen alien bodies were test dummies dropped in the 1950s caused quite a furor at the time within ufology. Some enterprising ufologists sold T-shirts with slogans such as “I’m not a dummy”. I uploaded a searchable PDF version of that report to this link:

For the sake of completeness:
(1) I also made available searchable PDF copy of the General Accounting Office report on Roswell (discussing the destruction of some government records):

(2) Back in the 1990s Clifford Stone wrote a document detailing his criticisms of the substantive part of the first of the above Air Force reports. I've uploaded a searchable PDF copy of that document (with Clifford Stone's permission) to the link below:
