TALLY HO!

Moving on to a WWII fighter plane, Wilson evaded the glance of a security attendant and climbed deftly into the cockpit.

Following his instructions, I remained on the ground making 'Engine Noises' while W shouted pilot-ey things like, 'Roger Wilco! Angels at Twelve 0'Clock High! Over and Out!'

When the constant rendition of engine sounds made me breathless, W sympathetically called down to me, 'Okay, New Dad – take a break from the engine noises, can you do some gunfire instead? Oh, and some explosions! Tally Ho!'
