That fall, Air Wave received an urgent call from D.A. Cole, requesting an immediate visit.  Arriving just in time to see Cole gunned down by what  appear to be ghosts, he and Static manage to route the murderers but Cole is beyond help.  Switching back to his identity as ,  Jordan before the cops arrive, the law clerk is quickly considered a suspect.  The murder weapon is found to be his gun and when he and the cops visit his office, fellow clerk Gump identifies the gun and shows that Jordan’s desk is empty.  Jordan is hauled off to jail, where is kept until Static arrives and lifts the keys off a sleeping guard, setting Jordan free.  Quickly switching to Air Wave, he tracked down the sheets of the used in the ghost disguises and called the laundry associated, found the owners address.  Arriving there he makes quick work of the gang and finds Gump, who eventually confesses that he had been operating out of the D.A.s office and murdered Cole, framing Jordan, when he was wise to it.  Air Wave quickly slipped back to his cell in time to be released and with Cole’s death, became the District Attorney himself (Detective Comics #66).

From there, Jordan matured in both his professional role and that of Air Wave.  Jordan was considered a somewhat intense workaholic, a solitary figure who took his work extremely seriously.  He became better known to the police, allowing more smooth operations in his costumed identity and was offered membership in the sprawling association of the All-Star Squadron (All-Star Squadron #30), though significant case work with that group has not been documented.  Although he largely advanced the mission of office through his Air Wave identity, primarily thwarting local organized crimes, he occasionally encountered more elaborate or advanced criminals such as Dr. Silence (Detective Comics #77) or the Parrot (Detective Comics #131). Static was ever at his side through at least 1948.

With the War over, Air Wave remained a local operator until 1948, when through circumstances as yet unknown, he was transported to Earth-One where he chose to remain or from where he was unable to return.  He re-established himself as a prosecutor  and built a new level with his wife Helen and eventually son Hal. Helen was herself likely a Jordan as Green Lantern of Earth-One Hal Jordan is their son Hal's cousin (assuming this is not an affection term but a familial one). It is known that he maintained some activity as Air Wave for likely 10-15 years but primarily acting locally and not being well known at a national level.  It is known that he had an encounter with Superboy, where he inadvertently saved the Boy of Steel’s career by thwarting a gold heist which was actually gold kryptonite which would have robbed him of his powers (DC Comics Presents #55).

At some point near the end of the 1950’s, Larry Jordan was working in his home office and planning a nightly patrol with a significant new upgrade in his technology, one that allowed him to become radio energy himself.  Tuning into the police radio, he was shocked to get a report on his own home.  When his technology backfired, converting only the costume into energy, he ran downstairs unarmed to find Joe Parsons, a criminal he had prosecuted. After a brief scuffle, Parsons fired several shots, killing Jordan and (in Parsons’ presumption) Helen and Hal.   After Larry’s funeral, Helen used the Air Wave costume herself to track down Parsons and bring him to justice before locking it away for the next decade (DC Comics Presents #40).  In the late 1970’s, she revealed the suit to their son Hal, who became the new Air Wave himself (Green Lantern #100).
