In recent months, viewers have seen Jackson Walsh deal with being diagnosed with tetraplegia as a result of a dramatic car crash, leading to him telling boyfriend Aaron Livesy (Danny Miller) and mother Hazel Rhodes (Pauline Quirke) that he wants to die.
As Aaron and Hazel attempt to prove to Jackson that life is worth living, the troubled former builder agrees to go on a skydive - something which Silcock opted to shoot for himself, rather than have a stuntman take his place.
"I had no desire whatsoever to do a parachute jump in my lifetime," the actor told TV Times. "But it was important for the storyline to show Jackson how good life could be.
"That's why I decided to do it. I knew it would be much better if they filmed me doing it for real."
Silcock explained: "With every scene I do as Jackson, we have to talk about it a lot beforehand. If I move a millimetre, then I am not doing my job properly. If I were really a tetraplegic doing a sky dive, I wouldn't be in the same harness I was in. They had to think of a way to strap me in and stop me from moving."
He added: "All the emotion you see on screen at the landing from me, Pauline Quirke and Danny Miller was genuine because we were all so glad that it went safely and we managed to do it. When I landed we shot straight away, so I had to remember the lines immediately, which was interesting!"
Silcock will leave Emmerdale in May this year and has promised that Jackson's final scenes will be "memorable".
