Philadelphia Experiment II (1993)

David Herdeg's participation in a failed 1943 experiment in radar invisibility has propelled him 40 years into the future. An aberration in his genetic makeup enabled him to pass through the portal of time. It has also made him sensitive to any alteration to the time continuum. Another disasterous experiment in 1993 sends a stealth aircraft through the time portal, into 1943 Germany. Simultaneously, Herdeg is pulled into the portal, and finds himself in the terrifying 1993 that resulted from a Nazi victory in World War II.
