Without knowing all the facts I'll still hazard a guess that the altimeter
settings given the crew were several points (maybe as much as 15-20) high.

 1. At 1:00 a.m. the ARTCC RDP computer may have been off=line for routine
    testing/maintainance as is often the case. This means the altimeter settings
    must be hand delivered to each sector by a teletype operator located away
    from the control room.

  2. The BDL weather sequence stated "presure falling rapidly". In this situation
    a delay of two hours (not too uncommon) could mean a large error.

  3. The tower, ALWAYS the best and most accurate source for altimeter settings,
    was closed.
