Above: Owen and the immortal Hawker Hurricane, RAF Museum

Karen was off Christmas shopping yesterday, so Owen and I went to the RAF Museum at Hendon, London.

What a wonderful place. Owen's too young to appreciate the significance of the RAF's role in saving Britain 70 years ago, but he loved the aircraft – and the hands-on gallery that explains the wonder of flight.

He was intrigued by the film about the famous bouncing bomb that the valiant dambuster squadron unleashed against Nazi Germany in 1943. What he doesn't know is that his grandmother regularly saw dambuster leader Guy Gibson in her hometown of Penarth during the war: Gibson's wife came from the seaside town.

Yet I was slightly uncomfortable as we had a snack in sight of the peerless Avro Lancaster bomber. Yes, I share the regret of many that the enormous sacrifice of Bomber Command crews was brushed under the carpet after peace came in 1945. (Back in 1942, the nation was grateful that the RAF was alone in taking the fight to Nazi Germany. Three years later, the politicians were more queazy about the resultant death and destruction.) But as we sat underneath the gun turret, I knew that I'd want Owen to understand that war is something to avoid rather than glorify.

Here's my video of our day at the RAF Museum.
