I'm just an old Airframe fitter, and undoubtably no expert in Helicopter operations, but, with the amount of damage done by the now two earthquakes how much more can a few roof tiles blown off make to the devastation that Nepal seems to have suffered. I read an analysis today in a national daily, that insinuated that our Chinook offer was held back because of both Indian and Chinese concerns of western military operations in "their own" back yard. It's a damn shame IMHO, these aircraft and crews could have brought some serious experience and expertise to bear in this unfolding disaster.
