Kailua and Kaneohe residents may notice increased aircraft and watercraft activity from 8 a.m. to 4 p.m. Tuesday about a mile northeast of Pyramid Rock Beach while the Marines conduct an aircraft mishap drill.

During this time, local and military emergency vehicles will respond to exercise incidents, according to Marine Corps Base Hawaii. Residents may see smoke from 10 flares between 9 and 11 a.m.

The Marines said the drill will focus on communication requirements and on simulatings events that could occur if there were an actual aircraft mishap.

Marines also get a chance to work with local, state and federal agencies to enhance readiness.
