So how about that, front wheel flew off!
I learned from the High Speed, High Horsepower sand rail gig to always check your car before going out on a Run. I make it a habit to check my wheel lugs just about every time I take the car out. YES I have found them loose on several occasions, especially after a night of whooping it up.
Double and triple check your parts and your work before heading out to terrorize. It will save your life and possibly others by doing so.
So moral of the story is know your car and check it often in all areas for loose this and that, bent or broken parts etc. Seat time will help you know your car very well.
