Yeah it is put when your under a time limit to remove these things and you dont have the manpower or the correct gear to dismantle these jets in the correct way its the easiest solution im afraid.
She was originally dismantled when moved from binbrook but that was many moons ago.
I have seen sevearl lightnings which have had there wings and fins cut and some you cant tell exactly where they were cut as they were rejoined perfectly.
The main thing is she was saved from the scrapman .

I know, I was there at Binbrook when it came into ASF for transportation.
