Boeing (BA) - Get Report shares traded at an all-time high Tuesday after the world's biggest planemaker unveiled an investment in supersonic business jet developer Aerion.

"Boeing is leading a mobility transformation that will safely and efficiently connect the world faster than ever before," said Boeing NeXt vice president Steve Nordlund. "This is a strategic and disciplined leading-edge investment in further maturing supersonic technology. Through this partnership that combines Aerion's supersonic expertise with Boeing's global industrial scale and commercial aviation experience, we have the right team to build the future of sustainable supersonic flight."
