Three departues from Zakinthos, two in 737-400's one in a 757. Both times in the 734, the crew ran up to full (or high) power on the brakes and both times they made am announcement explaining that this was due to runway limiting factors. One guy actually went into quite a lot of detail about the combined shortish runway, high fuel load and high temperature which I found interesting as a kid longing to learn to fly. Not sure how this went down with the more nervous pax. who no doubt had visions of us just mking it off the ground before the beach at the end of the runway. No such problems with the 757 though.
