engineers in cryo

I mentioned the hammerpede 

Apologies my phone is acting slow

Have a look above - hammerpedes have been mentioned a number of times.

It has to be the Engineer because it's the only lifeform in the vicinity of that PUP.  The hypersleep chamber slows down his life signs so there's no need to hold his breath - hence the intermittent lifeform reading leading Janek to believe it was a glitch.

No problem ali81 

quite clearly a long MAPPED corridor with NO sign of a ship

and there's ur ship,at the end of a long corridor

Correct.  Showing how close the PUP was to the sleeping Engineer when it picked up the lifeform reading.

how can the pup be in the chamber?the location of the ping is clearly in a place the pup had mapped. so where is the rest of the room? where is the rest of the ship in the first picture?

There's also a deleted scene where Fifeld an Milburn find a shed skin.I know it's "deleted" but perhaps something was running around in there.

the dead end clearly shows the pup cant map through walls or doors and the ping is located within its mapped area.

also the shreak heard during the hologram suggests something else was there with the engineers so where did it go?

deleted scenes r purposely put in the extras to show u the mind set of where the director was going. the skin and the shreek suggest that ridley is saying a deacon/ xeno or something else is down there

There isn't a strong belief that they were under attack from the Xenomorph 

"how can the pup be in the chamber?the location of the ping is clearly in a place the pup had mapped. so where is the rest of the room? where is the rest of the ship in the first picture?"

What makes you think it has to have mapped an area to pick up a lifeform reading?  It uses lasers for mapping - which can't get beyond the door.  It has bio-sensors to pick up lifeforms.

its clearly in an area where the pup has picked up the surrounding walls of the corridor. if the ping is beyond the door then why does it indicated the ping inside the mapped area if the pup cant pick up the inside structure of the cryo room?

xeno, yea I don't see the engineers running from the stationary goo like that. something is chasing them or has caught one of them

it could even be a deacon or a xeno just bursting from an engineers chest?

Chris ran a story little over a month ago about things we all missed about Prometheus,and he matched the scream to the Xenomorph from Aliens.I wouldn't count out the deacon either 

yea I saw that. id go with the xeno aswell. my theory is the derelict was part of several ships sent to wipe out the enigeers on lv223. huggers got loose which is why the derelict crashed but at least one ship dropped its cargo. if it was huggers then it would make sense a xeno, if already created, would burst from the engineer, though differ in size, as engineer and human make up is the same. the deacon is from a whole set of different circumstances
