The families of victims of an Ethiopian air disaster on Thursday criticized Boeing's plan to donate $100 million to unspecified charities and communities affected by two crashes, saying it was too vague and that families should have been consulted first.

Some of the families said Wednesday's announcement from the U.S. plane maker also triggered an avalanche of unwelcome phone calls from relatives and acquaintances who believed they'd just received compensation.

"This is unacceptable. They did not consult us, we only learned this morning," said Quindos Karanja, a retired Kenyan teacher whose wife, daughter and three grandchildren were killed in the March 10 disaster. "This is not in good faith."
