That's an old trick by the snow.
This is Vulcan B1 XA900 at RAFM Cosford around 1979, when snow lifted the aircraft and its two 25ltr sized concrete blocks in the air.
With a brush and a thaw, she came down fairly gracefully.
Sadly, after being left out in the open for too long, and with the arrival of B2 XM598, XA900 was unceremoniously towed round the back and scrapped.
