This is an experiment of nested puzzles.
The answer of each puzzle is necessary to solve the next one. Sometimes you have to manipulate it, sometimes you have to open your eyes (and mind).
Run, to Westminster Abbey!
Nevermind, to Gatwick, ok!
Please, don't waste time,
I want to keep my dime!
The original one is black,
never goes off track!
What's the answer?
Notes: I will add hints every 24 hours.
Sadly I couldn't add more than 5 tags, these are those I would include as well: rhyme, computer-puzzle, brain-teaser.
I accept partial answers, I will personally upvote those who solve at least 1 unsolved puzzle or submit a wrong, yet plausible solution.
Teamwork is appreciated!
