Ten of the most promising new regional aerospace start-up companies descended on El Segundo on Tuesday to pitch their futuristic concepts for the next wave of industry advancement, from orbiting cell towers in space to drones that communicate with each other.

The event, organized by new-tech business support company Starburst Accelerator, was held at The Aerospace Corp., the research and development arm of the adjacent Los Angeles Air Force Base.

Such meetings between legacy aerospace companies and energetic up-and-comers are becoming commonplace, as the industry works to keep up with a flood of technological advancements propelling the commercialization of low-Earth orbit.
