"As the world struggles to find out more information about the San Francisco crash landing, Twitter user Steve Baker used flight tracking website FlightAware to compare yesterday's Asiana Airlines Flight 214 (AAR 214) to today's ill-fated flight.\nHere's his Tweet:\n\nFlightAware data for AAR 214. Yesterday (safe) vs. today (crash). Much steeper descent today. #asiana #sfocrash #SFO pic.twitter.com/gwo00OkVwf\n\u2014 Steve Baker (@sbaker) July 6, 2013\n\nLook at an enlargement of the two descent paths (the part of the graphic that looks like a solid black wall):\n\nCompare the two flight paths, and you'll notice Friday's glide slope was much smoother than today's. Saturday's flight path suddenly veered downward just before the tail section of the plane hit the rocks on the shore at the end of the runway. \nThe reason for this deviation is still unknown. \nSEE ALSO: Plane Crashes While Landing at San Francisco Airport\n\nMeanwhile, an audio recording of air traffic control during the crash has surfaced: \n\nHere's the transcription, courtesy Time: \n\nFlight 214 cleared into land 28L at 18:21:12 Zulu\n18:22:27: Flight 214 calls ATC\n18:22:30: Tower says, \u201C214 Heavy, Emergency Vehicles are responding\u201D\n18:22:37: Flight 214 calls again.
