 There have been a number of on-ground collisions and others. Now, there's normally a number of close calls any given year. It just seems like they're happening in great abundance, along with planes. You know, Boeing may be the most aptly named company in America because the parts of their planes keep going and falling off in emergency land. A tire blew out in a plane taking off the other day. Two tires. Two tires. Two tires blew out at the same time. Amazing.
