Years prior, after a landing in snowy Detroit, I experienced a taxi moment in a 727 that temporarily installed my heart in my mouth. While the copilot and the flight engineer were enjoying friendly banter, I turned the airplane from a high-speed runway exit to a low-speed taxiway. In the process, I soon realized that the airplane had intentions that didn't involve remaining on the pavement. It wasn't until I resorted to activating reverse thrust on all three engines that the impromptu power slide was discontinued. Once my heart rate slowed to below cardiac arrest rates, I explained the extra noise to my crew. In that regard, I didn't want a repeat performance at JFK.
