sorry to nit pick cavey but he filled the bomb he made with used pinball parts. and kept the plutonium to power the time machine. lol

I agree with Beaky.....,
Just after the first test of the Delorian with dog inside, the combi-van full of libiyan terrorists returned to the carpark with machine guns a blazing......
Docs says somethign to the affect of "oh no, it's the libiyan terrorists, they must have found out i made a shonky bomb out of used pinball parts"
During all the panic, this is when Marty ('McFly', not 'Machine') jumps in the car, and outruns the terrorists, reaches 88mph and thus jumps back safe'n'sound in good ol' 1955....

I don't have it on DVD, but did see it 20+ times every friday night at "The Forum" in the city, for some odd reason....
