Yes it's only temporarily storage, hence the engines are still attached.
From the photos impossible to say ?
It would be interesting how long will those two 748 be in storage. The preparation for storage is serious ! We know that even for 6 weeks the engines are removed on 380 so .....
I think that if an aircraft is in Storage for 6-8 weeks or more and the engines are worth 40% of the planes value and have not been paid for they normally get removed and get used on another airframe ?
