Melchett01: ....I'm sure I once saw a video of a boom equipped aircraft that had been modified with a drouge element...
You may likely be remembering a KC-135 with the boom drouge adaptor mentioned in the post before yours. This was basically bolting a drouge to the end of the boom allowing the tanker to pass fuel to probe equipped aircraft. Used quite a bit in the first gulf war when many US Navy and coalition probe equipped aircraft needed tankers. The boom could not be used as boom as we know it on the same mission, so not really a "solution". If you wanted to return to boom operations, you would have to land and remove the drouge.
Nicknamed the iron maiden, as the steel basket at the end of the hose was less forgiving than typical drougues.
