Expect to see a large tethered balloon over Arlington National Cemetery tomorrow afternoon.

The balloon will be flying over the cemetery between noon and 7:00 p.m. to “to help conduct a height study of Washington, D.C.,” according to Joint Base Myer-Henderson Hall spokesman Stephen Satkowski.

The study will seek to determine the impacts of raising the District of Columbia’s building height limit.

The aerial photography company that’s coordinating the balloon, Falls Church-based Digital Design & Imaging Service Inc., was unable to answer any questions about the project, and referred us to a New York-based architecture firm, which so far hasn’t responded to a request for comment.
