What's up with ve­hi­cle's doors these days? This morn­ing I took the bus to work, and half-way we had to pick up a bus­load of com­muters strand­ed be­cause one of the doors of their bus wouldn't close prop­er­ly, and a bus can't move on with a door that's not closed. So due to this in­ci­dent some min­utes late I get on my con­nect­ing train. About halfway the train stops, and some­what lat­er it is an­nounched we can't move on be­cause we have a train in front of us on the track hav­ing a prob­lem with a door that won't close, and the train can't leave as long as all the doors aren't closed...

We can put a man on the moon, but we can't get him back to earth be­cause the door of the lan­der won't close?
