I once heard a story that the Blackbird could literally undergo a "burn up on re-entry" type accident. At first I thought this extremely far fetched, but upon hearing of the plane's fantastic altitude (80,000 ft plus ?) and speed (literally faster than a lee-enfield Mk4 bullet) I began to wonder. Then I discovered that the pilots suits are not your average G-suit, but are so over designed you could probably use them for space suits (though not Extra Vehicular Activity). By now I'm really doubting my original assumptions. A shallow dive could presuamably build up sufficient energy so that a rapid climb could convert this to additional height. I know that you don't have to reach vacuum to "burn up on re-entry" so the plane needn't be space-capable. Any thoughts or facts ? Thanx for any replies - Bruce.
