President Trump will attend the ceremony unveiling Boeing’s new 787-10 on Friday at their plant in North Charleston, South Carolina according to the White House. The 787-10 will begin flight testing this year and Boeing plans to start delivering to customers in 2018. The company states they already have 149 orders from nine different customers.

This will be his first visit to South Carolina since he won the Republican primary there in February 2016. Since he won the election Trump has criticized the costs of Boeing proposed replacement for Air Force One.

White House Press Secretary Sean Spicer confirmed the trip during his daily briefing.

“This visit will give the president an opportunity to celebrate a huge milestone for thousands of workers at Boeing, America’s No. 1 exporter, and the millions of American workers involved in aerospace,” Spicer said.
