dd & CH, people in the US have their minds in the consumer mentality of having the latest whatever. Most DU-folk are probably tapping away on their new or year-old iMacs, Mac Books, iPhones, and iPads, little thinking that many USAF and USN assets are 1950s designs built in the 1960s and 1970s. And the A-10s are a 1960s design built into the early 1980s. They couldn't imagine commuting daily to work - those who have jobs - in a mid-60s Chevy Impala or a mid-70s Toyota Corona.
Bear or Stratofortress, if it's operational and can deliver its payload, its age doesn't much matter.
