A sad, sad day for XR806 caused by a defuelling accident. Her forward fuselage still exists at BZN I believe

Last I heard was that it’s still there, see here for photos: http://www.vc10.net/History/bitsandpieces.html#XR806

The Il-62 is a different story. Basically it was designed with a more rearwards CofG making the trainer wheel a necessity. This was never needed with the VC10 but obviously loading the aircraft wrongly, using either cargo or fuel, can get many an airplane up on its tail.
