October 1st 1969 - Concorde's first supersonic flight.
Happy Birthday to a lovely lady, provider of wonderful memories.
Seconded Landlady, but the traditional; 'Many Happy Returns' is sadly no longer possible.
Also, its quite extraordinary that more than forty years have passed since that date - that's a whole grown up person!
Perhaps 'Happy Anniversary' to all the thousands of people who made Concorde what she is, would be more appropriate?
