how long did 250 state fair plan on having military sing for fireworks

I couldn’t verify how long the Great American State Fair planned the military singing segment for the fireworks from the information available here. The search results show the fair kickoff and separate 250th-celebration fireworks coverage, but not the specific duration of that performance.

What is confirmed

• The Great American State Fair kickoff was scheduled to begin at 7:00 p.m. in Washington, D.C..
• Separate 250th-anniversary fireworks coverage says the National Mall display was being billed as the largest in history.

• Other coverage mentions military flyovers and other patriotic programming tied to the 250th celebrations.

Most likely answer

If you mean the military singing portion of the fireworks program, the publicly surfaced coverage I found does not state an exact runtime. That usually means the schedule was either not published in the snippet available or the segment was folded into the broader opening ceremony rather than listed as a standalone act.

Short take

• Exact length: not confirmed.
• Event window: the kickoff started at 7:00 p.m.
• Fireworks context: part of the larger 250th celebration coverage

TL;DR: I can confirm the fair kickoff time, but not how long the military singing was planned to last.
