I understand that TU144 had structural problems that made impossible to carry people safely.
And about Concorde... I don´t have information about price but cost was really huge. It is often said that after the proptotipes, about 14 were build but the even point (where total sales equals the development and production costs) was about 100!!!, so the british and french taxpayers are the real owners of all fliying and grounded concordes on Earth.
