According to some dictionaries, usage examples of the verb "launch" include "launch an attack", "launch a campaign", and "launch an investigation", where the thing being "launched" is some sort of activity. But then there is this sentence from NYTimes:
New York City has launched a new plan to rescue moderate-rent apartment buildings that were swept up by private equity firms during the financial boom, then left to deteriorate as they drifted toward foreclosure when the new owners were unable to repay their loans.
A "plan" is not really an activity. So, could the usage in that NYTimes article be an error missed by the editor?
