REUTERS/Mike Blake (Reuters) -Surging demand for private jets fueled by hopes of economic recovery following mass COVID-19 vaccinations helped lift defense contractor General Dynamics Corp’s revenue in results posted on Wednesday. Shares rose more than 1% in morning trading to a 14-month high after the Gulfstream jet maker posted a 7% rise in first-quarter revenue as its aerospace unit’s sales picked up. The company’s business jet deliveries increased to 28 units from 23 a year earlier, amid increased coronavirus inoculations and easing travel restrictions.
