Can't see the video, as it's been disabled by you tube.
But the '140 was restored at RAF St.Athan during the 1970's and 1980s, and is now the one in the RAF Museum, Cosford. As far as I know, it's the only complete Me 410 in existence. I was allowed to get some detail shots of it a couple of years ago.
Don't know of any B-26 currently in the UK, or even in the last 30 years. Couldn't see it due to video not being available.
