Yes, but the ones currently still flying are the B-52H models that went into service 50 years ago. jhhaynes at earthlink dot net Just how safe is a 50 year old flying machine? You'd be surprised. Unlike automobiles, often underbuilt and subjected to a variety of environmental and chemical abuses, and human inflicted abuses, including ignored maintenance, harsh treatment by operators, poorly maintained roads, and spotty repairs, aircraft are operated in a much less harsh and/or hostile environment. While mechanical stresses in aircraft are significantly more intense than in automotive applications, aircraft systems are more robustly built at points of stress, regularly more aggressively maintained, and are not subjected to the horrors of salt, and environmental abuse. Cars are usually run hard and put up wet. Aircraft are operated in more circumspect manners. All major subsystems, and points of stress are inspected prior to every flight. Shock cooling doesn't happen with aircraft operated by competent pilots. Engines are cool-down run to prevent cracking. Maintenance is much more aggressive. Inspections are frequent and regular. Repairs are more carefully monitored, recorded and logged. In the event of spar rust, as on civilan Beechcraft Bonanzas, recently revealed, military aircraft are either grounded, or the parts replaced. And for the record the rust on the wing spars of Bonanzas, many of which date to the 40's, was revealed by annual and 100 hour inspections. So, a 50 year old military aircraft, while not maintained to the obscene and often punitive levels of civilian aircraft, are better maintained better than any civilian automobile, inspected at regular intervals for mechanical and structural insufficiencies, and are accompanied by records that go back to the first stringers being laid in the airframe. Myself, I drive a 60 year old car. I've gone up in much older aircraft many times with complete confidence. Some Countries have what they call MOT, or versions of MOT thereof. If that MOT was around here, Buku, Buku cars would be grounded. I am an old car nut. What kind of a 60 years old car do you drive? |
