Where do I start...
- Driving to the airfield and finding I've left the aeroplane keys at home
- Leaving the oil filler door unlatched and having to shutdown to secure it
- Getting taxi clearance and wondering why I'm not moving...forgotten to take the chocks out
- Wondering why the take off run seemed to be a little longer the usual and realising I hadn't set take off flap
- Not latching the canopy and having it try to open in flight
- Calling the next on route frequency without pushing the flip-flop
Not all on the same flight obviously.
