I did also hear about the TU-144 that it used to fly to Cuba.
Now, I only heard this one time so really am not sure if it is right, I expect that there are people out there who would now if
a) it ever did
B) how often / was it a one off.
What I also heard at the same time was that they had to ship replacement engines to Cuba for it because by the time it got there the engines were so done in they needed over haul and wouldnt have got back to the mother land.
Like I said, only heard it once so dunno if its true.
Hay Ewe - is that another sonic boom?
