Systems and methods for operating an accelerator driven sub-critical core. A fingerprint of the transaction topology in an IT infrastructure is automatically captured at various time intervals prior to the occurrence of an event leading to a problem, such as a failure, hard threshold violation, defined transaction violation or user-provided occurrence. The power system may include a propulsion unit operable to propel the toy aircraft and a power unit, which may include an energy source configured to supply energy to the propulsion unit.
