4/13/18, So I am up working on my roof before the 1.74" of precip in the forecast for Sunday and what do I hear about 6 miles away? Yep the spring visit of a four engine AC. A WW II B 17 shows up every year for the Great British Fly IN at Udvar Hazy and Dulles Intl. Airport. I have a feeling the weather will keep them grounded but I should start getting fly overs this afternoon and tomorrow.
