DPWN manager for both.
Also there are a large number of ex 767 drivers now flying for DHL Air and EAT.
Nearly all of whom are ex ETOPS experienced with several 1000's of hours on type.
Also the background of many Captains in both companies vary from B747 thru B727 and even B707 freight and passenger ops.
There are strong sentiments within DPWN to keep the aircraft European based, and unless you have the right to live and work in Europe that counts out the N registration.
It will not be like the UPS operation, unless your very cheap and prepared to out work over here for peanuts, then we have the former eastern block pilots who will undercut you even further.
The B.777's with Aerologic show DPWN's commitment to Europe.
The Losses in the USA, low Dollar $ returns, Unionisation and working practices, not a good sign for the future.
We also have enough pilots over here to do the job very well thanks.
N reg on DHL European / Mid East routes maybe one day but not soon.
