There is some overlap. Multiple shapes are reported at times.
A saucer might be overlaid by a triangle, the same place but at a later date.
A saucer seen edge-on becomes a 'cigar' at times.
Disks outnumber cigars/cylinders, and both appeared early on.
Flying triangles show mostly in urbanized areas near coastlines.
Rural FTs show around Indiana. One small cluster was near
Lumberton,NC in 1975 (79W x 34N) predated a major Belgian deltoid wave
by 14 years.
