Is there any way I can get the orientation of the drilling platform relative to the north-south axis and what direction was the helipad platform?
Consider this. If you have every gone plinking with a .22 calibre pistol or rifle and you were shooting at relatively soft beer or cola cans and you hit the can with the bullet from the side and not straight on you would get a oblong hole just like is on the helipad platform.
These smart bombs do not always drop straight down from the sky like Leo DiCaprio and Russel Crowe on Body of Lies want you to think. These smart bombs usually glide in like a space shuttle landing.
Therefore I pose the question

: Considering that only the United States CIA has the assets and the technology to have a B-2 Stealth bomber flying around at about 70K feet

; and suppose some creep in CIA Langley like a Russell Crowe type in the aforementioned movie gives the command to release ordinance

; and then he guides the bomb/projectile into the oil rig using the remote guidance and observation capabilities a spy satellite in a geostationary orbit about 22K miles above the equator; and looking where the major fire is located on the superstructure of the other pontoon, the trajectory of the bomb or projectile looks like it descended thru the helipad and impacted on the substructure on the other side

. What say anyone?
The North Korean mini sub nonsense is pure disinformation.
