US Airways 1651
Blew a tire on takeoff, circled to burn fuel and landed.
Note to staff: Looks like there are two flights on the above perma-link, the blown tire flight AND the one that went to KMIA, no diversion shown in the list.
Looks like flying around dumping fuel may have taken longer than the flight to MIA would have taken (if that flight time of 5-hours is correct–unless that includes the landing, repair, then re-departure time…).
