It is not generally known that a few years ago the Jewish community in Madrid discovered at the last moment that they had no horseradish for making chrayn for Pesach.  All the countries they asked replied in the same way, "Sorry, we have none left to send you."

So, in desperation, the Spanish Chief Rabbi called his friend in Israel and begged him to immediately send him some horseradish by air freight.  He agreed and three days before Pesach, a crate of the best grade of tear-jerking Israeli horseradish was loaded onto an El Al Flight to Madrid.  All seemed to be going OK but when the Chief Rabbi went to the airport to pick up his desperately needed horseradish, he was shocked to learn that there was a strike and that no crates of any kind would be unloaded at the airport for at least four days.

So, as it is said, “The chrayn in Spain stayed mainly on the plane.”
