 There is quite a bit of alternate footage on the airline version. Such as:  Hummel holding and pointing his gun at Masons head. In the theatrical  version, his gun forearm is being steadied by his other forearm as he says,  "That was a bad move, soldier". In the airline version, he is holding his  weapon with both hands, and dialogue is inflected with a more threatening  tone. He is made to be more threatening by alternate takes of dialogue, as  seen in his takeover of Alcatraz from Ranger Bob and his ransom demands.  There is also some alternate footage when Goodspeed is disassembling the  first rocket. Also, some of the soldiers frantic voiceovers in the beginning  have been removed; the "Rube Goldberg" sequence that introduces Goodspeed has  been removed. The airline viewers first introduction to Goodspeed is the  Sarin Gas incident.
