Donald Gennaro expressed his concerns to John Hammond during their ride together on the jet to the helicopter. He was concerned that Isla Nublar had postponed its opening, and that the delays were unusual. Hammond soothed his fears by assuring him that these delays were the result of the normal automated glitches, and problems with their computer systems. Hammond proceeded to dismiss the construction accidents as being not a reason for delays.
