hey Dan
No offence to you but me just being curious here.how can you judge the speed of an a/c that too a big one like the buses and boeings while travelling as a passenger.I think the inflight entertainment system shuts off just before landing unless they have the channel showing cameras outside the a/c(EK has this facility and its really awesome to see the pilot align against the centerline and land.truly amazing) .
Cheers.
