She may look that way but thats because she is being prepared for painting. This had be halted over the winter.
Interested to know which panels you saw open. If it was the belly holds, then a closer inspection would show that they are infact locked in an open position to allow airflow through the aircraft...without allowing any unwelcome guests.
With luck we should have her back in RAF Transport Livery by June/July and taxing at the Air Day.
