Bloomberg is reporting that Google's parent company Alphabet is tightening the reigns on Project Wing, a unit of Alphabet's X research lab, by "trimming headcount and shelving initiatives." What's more is that they've reportedly nixed a partnership with Starbucks. Bloomberg reports: Following the departure of project leader Dave Vos in October, the unit also froze hiring and began asking some staff to seek jobs elsewhere in the company, according to some of those people [familiar with the decision]. The decisions are part of a broader Alphabet effort to rein in spending and try to turn more experimental projects from loss-making risky bets into real businesses. Drones are in a particularly knotty place. U.S. federal regulation does not yet allow for delivery, except in select test zones. However, Alphabet's deceleration comes as other technology companies, including Amazon.com Inc., plow money into drone delivery. In August, Project Wing won approval for test flights at a U.S. site, part of a White House effort to encourage unmanned vehicle delivery. Then in September, Alphabet announced a new foray: a partnership with Chipotle Mexican Grill Inc. to deliver food via drone at Virginia Tech. Alphabet was in advanced talks with Starbucks and had tested delivery with the coffee-chain operator, according to two people familiar with the plans. Those plans were nixed, largely over disagreements about the access to customer data that Alphabet wanted, according to a former X employee.
