Just looked at the NASA rule book and it says that the M2000 rating is not acceptable, and that effective Jan. 2012, even the M2005 will not be good enough.Seems like some planned obsolescence BS rather than the old ones being "unsafe." I'm not sure if that's only for HDPE or if it's for Hyperdrive, too. There were way too many pages. Looks like I may not get to use my helmet.
Are you sure you aren't looking at the racing section? Everything I see for HPDE (and Hyperdrive) says 1990.
