I posted this some time ago, but thought it was relevant again as we mark the 75th anniversary of the liberation of the Auschwitz death camp.
Back in 2003, to mark an anniversary of the Polish Air Force, three Israeli Defense Forces pilots were invited to participate in the ceremony and flew their F-15 jets over the camp in a show of remembrance and strength.
Very moving for sure, but a few in Israel at the time suggested the fly-over was inappropriate and in some respects disrespectful to the memory of the victims.
