I also find trousers a bit strange. I ventured out in trousers one morning last week for the first time in over a month and changed into a kilt at lunchtime. Yesterday was a blustery day and I flew a radio navigation exercise to Prestwick and back. Kilts aren't ideal for a windy day. Kilts aren't ideal for climbing into the cockpit of small aircraft. Combine the two and I opted for trousers yesterday, which felt strange all day and several people asked where's the kilt today.
