N141B
N141B was also featured in Highway Patrol episode 128 "Train Copter" which aired November 1958. The Highway Patrol helicopter is called into action to pursue a train carrying a bank robber and $35,000 in stolen money. Actors Broderick Crawford and William Boyett follow a Southern Pacific Daylight passenger train and the bank robber jumps from the baggage car. This appears to be filmed in the Northridge area of Los Angeles County. Features some very nice low level flying but I don't know who the pilot was?
