I read the twitter exchange
(a) @FreqDLTrvlr is not DHD, see his note-
"@oupiglet Wrong person. I didn't hassle any agents. And I wasn't in the BE lounge in E."
(b) from the twitt exchange, It turns out that there is more than one person with delta hat! so it may have been an organized distribution by DL!
(c) Where is my popcorn? I hope @FreqDLTrvlr would be able to help in the FT search for DHD...
