From what I remember the water on the BAC 1-11 only served to allow you to make even more noise and give you a warm fuzzy feeling that you were actually developing more brute power. Oh God I remember those water takoffs from Sicily with 114 pax with their buckets and spades trying to get to Luton, scraping by FL 200 by about Pisa.
Tell the kids of today that and they'll never believe ya.
