RADIO EQUIPPED BUSES SPEED PASSENGERS TO DETROIT: These two busses are part of the fleet of special carriers which take airline passengers to and from Detroit. Note antennae for two-way radio which provides direct communication with the field at all times. Thus if traffic or weather conditions slowed the bus, the driver could advise the dispatcher at Willow Run of his estimated arrival time, and passengers could be scheduled on a later plane, or the flight held up a few minutes. Due to smaller volume of passenger traffic to Ann Arbor, no such special service exists for airline passengers needing Willow Run-Ann Arbor transportation.
