@ Mazdadriver: I believe HH have flown some adhoc flights for shell and if I am right their website also stated they have been audited by Shell.
But all of this is of no importance anyway.
DC is the new Shell-slave. I hope they do well and keep their company as it is, without getting completely influenced by shell.
They are unlucky at the moment because of U/S aircraft and I doubt they have managed to get the proper spares at the bases but give it some time and all will be good.
