I've been to #BletchleyPark today with my friend & ex BP colleague Catherine for a 'friends' event with two #veterans: Betty Webb & Pat Owtram. I've met Betty many times (I've even had dinner with her #humblebrag) but it's always great to hear her speak, and Pat Owtram was just as inspirational. They're both 100 years old.

We saw a handful of old colleagues, experienced two #flypasts (the #RedArrows and a #LancasterBomber), located a fire, and (at long last) visited the "new" Block A exhibition and the temporary (but repeatedly extended) exhibition "The Art of Data", which is in all but name a #maths exhibition. Might blog about that bit later.
