Ejection Seats on Orbiter Columbia

Did you know that NASA Orbiter Columbia OV-102 had ejection seats? The first four STS missions flown by her had them active, by STS 5 they were disable and removed by STS-61-C. They were the same ejection seats used as the SR-71 and could only be used to Mach 4. #spaceshuttle #spaceshuttlecolumbia #ov102 #ejectionseat #nasa #sr71 #usaf #aviationsafari #aviationpreservation #boneyardsafari
