On my way to Warsaw after the catastrophic plane crash which killed the president, the head of the central bank, the army chief of staff, many MPs and senior government figures.
One colleague in Warsaw tells me "almost an entire generation of the political establishment has been wiped out".
People at Heathrow see our camera and one person asks if we're heading to Poland. I tell him yes and he crosses himself.
"It is awful, truly awful."
Perhaps it's my imagination but even though the flight is very quiet, more people than normal seem to be paying attention to the safety brief.
Warsaw airport is normally a lively, busy place. Tonight even though there are many people here, it is noticeably quiet. A loud child is quickly shushed to silence.
The drive in from the airport is quick. The streets are very quiet for a Saturday. Many buildings are flying the Polish flag, draped with a black ribbon.
