A 1964 Secret Service report stated:
QUESTION: Are there any buses routed by the corner of Jefferson and Marsalis Streets that are also routed in the vicinity of any airports in the southern part of Dallas?
ANSWER: There are no city buses routed in the vicinity of either Redbird or Skyline Airports. It is possible to ride a Greyhound Bus to the vicinity of Skyline Airport which is located adjacent to Highway 77 South, and an individual would be able to stop the Greyhound Bus to be let out at the Skyline Airport. The Central Texas Bus Lines can be boarded at, either the Continental Trailways or Greyhound Bus Stations, or flagged at intersections along the route; travels to Duncanville, Texas, and is routed past the Redbird Airport. It is possible for an individual to request the bus be stopped in the vicinity of Redbird Airport, and thereby to have access to the airport.The problem though is that freeways don’t have intersections - that’s why they call them
freeways. So where exactly could Oswald have stopped a bus on freeway 35? Technically he could have stopped one at gunpoint using his pistol, but his first preference would probably be to flag the bus down normally so as not to draw attention to himself.
There is some debate as to whether Oswald was walking east on 10th street (and was then stopped by Tippit) or if he was walking west on 10th street, saw Tippit, and then turned around and began walking east. This would have consequences as to which intersection Oswald was heading towards on Interstate 35 (if that is indeed where he was going).
