Taber MacCallum

He is co-founder and former CTO of World View Enterprises, a stratospheric balloon company using its un-crewed Stratollite for remote communications and sensing.

Prior to World View, MacCallum served as co-founder, CEO and CTO of Paragon Space Development Corporation, a designer and manufacturer of hazardous environment life support equipment.

On June 18, 2020, Space Perspective announced its plans to balloon passengers to nearly 100,000 feet (30,000 m) or around 19 miles (31 km) high into the sky above the surface of the earth for roughly US$125,000 per ticket.

The Stratollite[6] is a remotely operated, navigable, uncrewed stratospheric flight vehicle designed and engineered to station-keep over customer-specified areas of interest for long periods of time (days, weeks, and months).

[citation needed] MacCallum's training for Biosphere 2 led him to work on a research vessel, eventually holding every level of command, sailing to over 40 ports and over 30,000 nautical miles (56,000 km; 35,000 mi) around the world.
