The letter from the EU commission was a response to a letter from Palle R Jensen, RUF International to Transport Commissioner Loyola de Palacio informing about the progress regarding RUF and asking for information about a specific program (Marco Polo).

Some quotes from the response letter:

"We are pleased to note the progress with the RUF Dualmode Concept (RUF) and the support you have received from the European Union's research programmes."

"I would like to wish you success with the further development of RUF and would be pleased to be kept informed about your progress."
