Another true story ....
Yesterday, I & another woman PPL, flew to Cambridge. We were both wearing OUR usual pilots' "uniforms" of tee-shirt & jeans (& of course hand-bags

)
This proved useful, when we did our interpretation of Cambridge's Park & Ride service......
..... Well we did PARK the aircraft at the airport, walked the 200m to the Park & Ride carpark, mingled with the shoppers, & caught a RIDE on the bus into central Cambridge, for the bargain price of £1.40 return. (You can now do the same at Norwich).
I am not sure that we would have passed off, as shoppers, in flying suits with 4 gold bars!
