I'm curious if the US defense committees were aware of this (and other) pilot reports as part of their duty to oversee defense programs. My guess is that they were not. Perhaps we will have to reconstitute the special F-35 oversight committee that recently ran its course after the program's restructuring a few years ago. This (leaked) report is bad news for those who want to devise a block buy scheme to avoid the stiff requirements of a US multi year procurement program.
