This Beech served Dynamic Av Lease at the time the picture was made. The King Air is former C-21C 76-22553 of the US Army. It was transferred to the "civil" market on 5 Feb'99 as N255AG with AGES Aircraft Sales & Leasing. In that same month the Dynamic Aviation Group Inc. started to operate the aircraft, most probably in support of US Government agencies. On 24 Apr'01 the Beech was reregistered to N612SA and kept that one until Dec'10 when it became N42J with Dynamic AvLease Inc.. In Mar'19 the King Air was converted to Beech A200 with still Dynamic AvLease Inc.
