Taxi Speeds
A bit off topic, but always had a chuckle at the ATC call: (after a brief hold on a taxiway) "Ryanair xxxx after the KLM 737 has taxied out you are cleared to hurtle on to stand 1".
The aircraft in question had done a good Alonso impression until asked to hold for his stand. (Sorry, this wan't Ryanair bashing, just funny...)
