The Polish pianist Krystian Zimerman no longer performs in the USA, partly since an incident in 2006 when he arrived at JFK airport with his custom-engineered Steinway instrument to discover, after clearing Customs himself, that he could not collect the piano as it had been destroyed on security grounds by the TSA.
What reason was established for the instrument's destruction?
There had appeared to be pockets of an unexplained substance tucked into various obscure parts of the mechanism
The chemical composition of one or more of the specialist glues in the soundboard had closely resembled the 'fingerprint' of certain forms of explosive, and the authorities could take no chances
There had been specific terrorist intelligence about an upcoming and unconventional form of bomb being sent from the Middle East via eastern Europe
Zimerman had been the victim of identity theft by anti-Zionists, with a point to make about the freedom of people of Jewish descent to travel while Palestinians and others are walled in and out of parts of the Holy Land, so any unusual freight consignment against his name was marked for automatic destruction
