2 defunct satellites nearly crashed into each other above USA

Two defunct satellites in danger of collision passed by each other without incident above USA's Pittsburgh on Wednesday. The satellites, travelling at a combined velocity of 53,000 kmph, had been predicted to pass within 40 feet of each other. The satellites in question are an Infrared Astronomical Satellite (IRAS) launched in 1983 and the GGSE-4 satellite, launched in 1967.
