Visible crew/equipment: After Station 51 is dispatched to the structure fire, en route Squad 51's engine stalls and starts again, then while they continue driving when the dispatcher cancels the run the reflection of the filming vehicle can be seen on the squad's surface.
Visible crew/equipment: When Charlie stops at the station to service Engine 51, while Roy and John are trying to service the squad, the multiple reflections of location array lighting are visible on Charlie's squad, and on Squad 51's spotlight.
Family Ties - S6-E16
Visible crew/equipment: During the structure fire, while the first teenager is being carried down the ladder from the attic window, in the two closeups of Captain Stanley if we look past Engine 116, in the background we can see Universal Studios' GlamorTrams driving by, which provided tours of the studio's backlots. This rescue was filmed at the "Corner House" located on the original "Colonial Street" in the studio's backlot.

Other mistake: Dr. Morton notifies the operator of the Code Red in room 127. Everybody knows room 127 is Dr. Brackett's office.
Family Ties - S6-E16
Visible crew/equipment: After both siblings are carried out of the burning house, when Roy kneels down beside the boy and leans forward to set down the drug box, the bulging outline of Roy's mic transmitter is visible (till the end of the scene) at the front, left side of his shirt, and note that the actor even touches it, possibly to make sure it didn't move out of place.
Family Ties - S6-E16
Other mistake: Before the fire in the patient's room, which is caused by liquid shorting out the clock radio, we can see the tape covering the brand names of the baby powder and the clock radio.
Family Ties - S6-E16
Continuity mistake: When Station 51 is dispatched to the 'traffic accident with people trapped', time out is 10:23, but when Roy takes the man's blood pressure his watch reads 9:00, and when Johnny's on the Biophone with Rampart his watch reads 11:25. Then when John gives Rampart the second set of vitals, his watch reads 2:20.
Family Ties - S6-E16
Revealing mistake: When the fire is started in the patient's room, which is caused by liquid shorting out the clock radio, at the end of the hallway we can see through the window's open shades and the view right outside the window is quite pretty, but in all of the exterior shots of Rampart there is no such view on any of its sides. It's a matte painting.
Family Ties - S6-E16
Visible crew/equipment: At the house fire, when Chet finds the teenagers in the attic, just after Marco climbs in through the window, we can see the moving shadow of filming equipment (looks like the boom) by the stool.
Bottom Line - S6-E17
Revealing mistake: While the guys are eating chilli at the table, when Station 51 is dispatched to 'man down', notice that when they're at the scene, both paramedics are wearing their jackets and Johnny is wearing his helmet. We never see Johnny's face in any of the wide shots, because the entire time it's the double with Roy. We only see Johnny alone in a few closeups, pickup shots which were filmed later, and we can see the style of the houses in the closeups do not resemble the houses in the other shots. The real Johnny is back, once they reach the hospital.
Bottom Line - S6-E17
Visible crew/equipment: A man walks into the ER with a white phosphorus burn on his arm, and when they wheel him into the treatment room, an actor's T-mark is visible on the floor below the gurney.
Bottom Line - S6-E17
Visible crew/equipment: When the guy walks into the ER with the white phosphorous burn, the outline of the lavalier mic transmitter is visible on the back of Dixie's uniform.
Visible crew/equipment: When 51's guys are at their practice game, the gymnast is injured and the outline of the mic transmitter is visible on the back of Johnny's T-shirt. (00:16:40)
Revealing mistake: When Station 51 is dispatched to a man trapped at World Picture Corp, just as they reach the entrance to World Picture Corp, the Sheraton-Universal is seen on the corner, and the street sign for touring Universal Studios is visible as well. (00:19:45)
Revealing mistake: At World Picture Corp, when John and the guy with the broken clavicle are lowered from the overhead joists they're both wearing lifebelts buckled around their waists. The problem is that once they reach the ground, we can see the additional carabiner attached to John's lifebelt, which is also attached to extra green support protruding from under John's shirt. We can also see the victim's additional carabiner going under his flannel shirt. While Roy is on the line with Rampart, when John removes the victim's lifebelt, the extra carabiner is still protruding from under the victim's shirt and John places his hand over it. (00:27:00)
Visible crew/equipment: After spending all night on the job, when the tired guys of 51 are at the basketball game, the outlines of the mic transmitters and wires are visible on the backs and sides of 51's jerseys, particularly when Roy gets injured. (00:36:00)
Continuity mistake: After winning the semi-finals against 16, when Chet walks into the kitchen in the closeups John's holding the newspaper filled with photos on the page facing out, but in the wideshots an entirely different page faces out. (00:45:00)
Revealing mistake: When Station 51 is dispatched to the gas explosion at the cafeteria, during the actual rescue the four firemen we see in closeup in the cafeteria are supposed to be Roy, Johnny, Chet, and Marco, but it's really odd that all are the doubles, very obvious in the closeups. There's little dialogue during this scene, which was dubbed later in ADR.
Visible crew/equipment: After winning the semi-finals basketball game against 16, when Captain Stanley, John and Roy walk into the kitchen, Roy and Cap stand near the stove, and two tape marks are visible on the floor.
Visible crew/equipment: At World Picture Corp, after the rescue of the guy with the broken clavicle trapped up on the joists, Morton tells Roy to transport the patient as soon as possible. It cuts to a shot of Squad 51 following the ambulance to ER receiving, and as they drive through the underpass, it's from the POV of inside the squad. Some location lighting becomes visible on the right side, and the reflection of the cameraman's legs are visible on the windshield, as he's seated in the passenger seat. We know that one of the paramedics is in the ambulance, so there should only be a driver in the squad.
Answer: I was rewatching a few first season episodes of Charlie's Angels (1976), and in S1xE6 "The Killing Kind," I recognized the same actor. So, to finally fully answer your question, the two baseball players in School Days are played by Rod Perry and Sean Fallon Walsh.
