I had an MG Midget years ago. This car was a hoot to play with being go cart sized going 50mph felt like doing 75 with anything regular size. I'm kinda tall so I could only get in or out with the top down.
Anyway I got done playing under the hood tweaking the timing/ valves and tuning the carbs, if anyone has worked on these knows, it's an ordeal that goes on there. Dropped the hood, (no safety catches in those days) fired her up and headed down the street. I made a right onto a main road that had a nice long straight run and opened her up!
I got about 50 yards about 35 mph and the hood folded back over the windshield! Talk about sh!!tin' razorblades! I couldn't see a thing in front of me, held the steering wheel straight and stomped the brakes to a skreeching halt.
Got out and checked my shorts. A Woman who was coming the opposite way saw it happen, stopped and wanted me written up! I just put the hood back down and limped her back home.
