Loch Raven Dam UAP — USAF Electromagnetic Effects Investigation
Two engineers observed a large egg-shaped object hovering silently over the Loch Raven Dam bridge. Their vehicle engine and lights failed during the approach. Upon the object's departure in a flash of white light, both men experienced sunburn-like symptoms and were examined by physicians. The USAF 438th Air Intelligence Service Squadron formally investigated and the case was classified 'Unknown' in Project Blue Book.
