we can but what's even cooler is that if one of us is at home and the other is flying in on a certain flight, which happens to fly over our house at around 5pm into BOS, the person at home--a 45minute north of the airport--can drive there at that moment, thru traffic and into the airport and have enough time to sit and wait because the flight coming in is international so they have to go thru customs and immigration. My wife flew alone overseas with one of our children in Sept and I used the fact her flight went over head to tell time in this way. made it there with enough time to make it but not have to sit and wait for an hour in the lobby.
