The pilot on a recent flight on which I was a passenger aborted a take-off towards the middle of the active runway. I had never experienced that before. We had waited at least 25 minutes in a queue of aircraft before we finally reached the runway. When the pilot announced that we will circle around and try again, I thought “Oh, great — another half-hour in line.” However, we turned around on the taxiway between two active runways while the other aircraft in line waited on the other taxiway. Our aircraft then took off successfully without losing our turn. Later on — while in flight in a regional jet aircraft — the pilot explained that just as we were taking off, the control tower instructed the pilot to abort the take-off due to a pilot from an aircraft landing on the active runway next to us warning of potential wind shear in the area. Sure enough, the take-off was rather bumpy and erratic, but the flight was smooth from there on in. I had never felt an aircraft brake so abruptly — especially after attempting to gain enough speed for taking off. Has anyone else experienced this — or, at least, an experience similar to this?
