The secret of UAV

"Our scouts recently reported seeing an unidentified flying object over Yanov station. A UFO, in other words. Before you ask any stupid questions, a UFO isn't just some flying saucer with Martians in them. It could be any flying object, from a piece of cardboard to a meteorological probe, as long as eyewitnesses were unable to identify it. Got that?"
-Duty stalkers in Yanov

But really it is just a RQ-4 Global Hawk is a UAV (Unmanned Aerial Vehicle) in service with the US Armed Forces.

In order to find the UAV aircraft and start the mission, you need to reach the northwestern part of Jupiter, just north of the Ash Heap anomaly.(look at the map below)

From stashes
-A note to Ghost and medical supplies.
-A note to Strelok and a lot of various ammo.
-A note to Fang and Strelok's SGI 5k (unique weapon only 1 in the game)
The way this quest plays out depends on who the player gives the module to and when one visits the stashes it recorded.

If you give it to Novikov, he returns the unblocked memory module after one hour and all the caches are shown on the map, this costs 2000 RU.
If the player gives the module to Nitro, it takes an hour and costs 1000 RU but the mission changes.
As soon as the player gives the module to Nitro, all stashes are emptied except for the notes and Strelok's SGI-5k.
If the player returns to Nitro after the work is done, he will only give the stash coordinates and Senka's body will spawn near the last stash visited by the player, carrying the unblocked memory module (described as having been unblocked by Novikov) and other items that would normally be in each of the previously visited stashes.

and loot from the body of Senka's shown below

The unblocked Memory Module can be sold to Owl for 500 RU. Strelok's Group notes can also be sold to Owl or used near the end of the game for the A Keeper of Secrets achievement.

Any and all feedback will be much appreciated.
