Vietnam War vets build Bell ‘Huey’ Helicopter for Philly exhibit [photos]

“The 1968 Exhibit” at the National Constitution Center will feature a personal touch from Vietnam War veterans.

Vets gathered at the NCC Friday morning to help assemble a Bell “Huey” Helicopter used during the war.

The exhibit opens June 14 and runs through Sept. 2, and will focus on “one of America’s most colorful, chaotic, culture-shifting years richly to life.”
