The whole "Canton Engine Saga" brings into sharp focus one of the hazards of being involved in a project of this nature - when someone/something famous is involved, one of the natural human tendencies is to want to be helpful/involved/part of it/ etc.
Which can lead to some of the truly bizarre "recollections" that TIGHAR has had foisted upon it over the years. The Canton engine was not one of those. It was something that seemed, on the face of it, to be worth checking out. It was only much, much later that documentation was located that enabled TIGHAR to put Bruce Yoho's recollections in their proper perspectives.
