On time or not, surely staff or not,it amazes me when people are so slapdash with their choice of provider to hurl you through the air at 500 mph, at a cabin altitude of 8000 feet, in a tin tube pressurised at 9 psi !!
Recent dutch report on an aborted take off at schipol made interesting reading. First officer aborted the take off beyond V1 (decision speed, you CANNOT decide to stop above this) , because the aircraft 'didn't feel right',no mechanical faults found, capt was lucky to stop in the remaining distance.Capt had 3000hours flying , the FO 2000.
Most airlines won't even consider promotion below 4000 hours .
