D-AHND is a CL604 registered to Saigon Capital (NL) B.V. - visited Luton 30th March (see my pics). The operator on the day was listed as Saigon Capital Aircraft Management.
C/N is 5477 and based at DUS.
I'd be interested to know if this was the aircraft that brought the Libyan Foreign minister back to the UK when he defected?, it arrived in from Dgerba (sp?) Tunisia and spent a few hours on the Signature Ramp at LTN with some interesting black cars around it on arrival!
