Captain Picard greeted his distinguished visitor.
"Welcome on board The Enterprise Admiral, it is a great honour for us to have a living legend with us on our first mission."
"Thank you Captain. NCC-1701-D, I wonder how many more starships called Enterprise will have this designation?"
"Plenty more letters in the alphabet Admiral."
"Yes there are Captain, I was glad to hear that Starfleet has commissioned another Enterprise."
"So what do you make of this one Admiral, how was your inspection of the medical facilities?"
"Amazing, I wish I had some of your medical equipment in my day. However, not all of your fancy machines can replace the skills of an old country doctor. How did you get Beverly Crusher as your Chief Medical Officer? Rumour had it that she was going to promoted to head of Starfleet medical. You have got a good doctor on board Captain."
"I was very happy that my old friend Dr. Crusher agreed to join the Enterprise. I have known Beverly a long time, I used to serve with her late husband Jack on the Stargazer. She will be pleased to know that you approve of her joining the Enterprise."
"I am sure she will."
"How many of the other Starships Enterprise have you seen Admiral."
"They wanted me to accompany Kirk and Spock at the launching of the Enterprise NCC-1701-B but Jim ended up with Scotty and Chekov. I always regretted not being there, I think I could have saved Captain Kirk if I had been with him. I made sure I was there for the launch of the Enterprise NCC-1701-C, that was the last time I saw Spock. I still hear from my Vulcan friend every now and again but he is busy being a diplomat these days. Now if you will excuse me Captain, I understand that there is a shuttlecraft waiting for me. Thank you for the opportunity to see your new ship, she has got the right name. You treat her like a lady and she'll always bring you home."
"Thank you for honouring us with your presence Admiral. Picard to Data, could you come to my ready room and escort The Admiral to his shuttlecraft…."
