I was working at Edwards AFB about 1990 when a B-1B came in - it had been doing tough & goes in DALLAS and the nosegear hung up. They air refuelled and went 1500 nm to Edwards to land on the lakebed.
Had test pilots from the manufacturer and the USAF flying chase on each wing, and they tried everything in or out of the book to get the gear down. Finally the sun was setting so they brought it in for a picture-perfect landing. $20,000 of sheet metal damage. Our airshow was that weekend so they put it on display for the public to see.
I saw the crew in the O club that night - they had left home in the morning for a 2 hour local and were in California by nightfall - they partied hard that night....
