Beta Technologies, Vermont’s homegrown electric airplane company, has spent about $22.6 million snatching up at least 13 properties around its base of operations at the Burlington International Airport over the past year. And this summer, the company announced a plan that would more than double its footprint in that part of South Burlington, to 100 acres, over the next decade. If this master plan is green-lit by the city’s Development Review Board, the company would begin renovating some buildings, tearing down others and constructing new ones. What’s emerging in this eastern section of South Burlington along Route 2 could effectively be called “Betaville.” Fueling the massive expansion is the $1 billion the company raised by going public last November. Founder and CEO Kyle Clark said Beta will double its local workforce, adding about 1,000 employees by the middle of next year as it competes to bring its innovative electric aircraft to market. buff.ly/PzSpBaT
