Top Ender Giggles - Think it through!

Yesterday we went to an Airshow. As we came off the main road to join the queue into the airfield we began to see some of the aircraft arriving for the show later that day. We all sat in the car watching the planes in the holding pattern waiting to land before Top Ender spoke;

"I guess there must be an Airshow nearby."
"Top Ender, where are we going today?" Asked Daddy
"Erm...An Airshow! I forgot!"
