Sorry Skytrain. Language barrier and total stumble flat on my face on my part. It's me who should apologize
. I only meant to say 'Oh my!' in a bit stronger way. Picked wrong expression and tone.
I find the challenge just perfect and cannot understand how two guys were able to get there when there was so little available about it in the web. Just tried to give some insight about the builder and plane.
In summary: I am sorry and meant no offense!
