This is the second dream I have had in two days concerning a plane.
I was about to go on holiday and the plane was just about to leave the runway when it hit a 4x4 car and turned the car on to its roof. The man got out and was cut and bruised. The plane started to go again and then suddenly stopped as there was some damage caused by the crash. We all had to get off the plane and wait for another, however during this time, my luggage got lost. I am not sure how the dream ended I just remember an airport employee helping me look for my bags.

I think you have just hit the nail on the head - although I won't go into detail.
Thank you.
