Movement tracking, radio log and overdue vehicle procedure

Travel times: 25 km tarmac = 30 min; 15 km dirt road = 30 min; 18 km dirt road = 36 min; 24 km dirt road = 48 min; 35 km tarmac = 42 min.

Mike 3 did not call at P3 even though it passed it (the flat tyre occurred 10 km after P3): it therefore missed its call point. Between 14:40 and 16:20, 1 hr 40 without contact, beyond the 60 minutes allowed.

Expected time at P3 (actual departure 14:40): 15:28.

• 15:58 (+30 min): Mike 3 overdue. The operator calls the driver on the radio, then by phone, then the passengers' phones, then the satellite phone; they record each attempt and its result in the log. They may also ask Site Bravo for the actual departure time.
• 16:13 (+45 min): no contact: they inform the security focal point (time of last contact 14:40, route, passengers, attempts made).
• 16:28 (+60 min): the security focal point activates the incident procedure (crisis cell according to the plan, gathering information from other organisations and contacts along the road, preparing a possible search before the 17:30 curfew).

What the log shows: no action between 14:40 and 16:20; the operator simply said "Copy that" at 16:20. The vehicle was overdue for 22 minutes without anyone trying to reach it or alerting the focal point. After arrival, the operator should have recorded the cause (flat tyre, area without network), and the focal point should remind the driver of the mandatory call at P3 and check that the vehicle's satellite phone works.

• Mike 2 leaves at 06:20, before the end of curfew (rule 1): the departure was already planned at 06:20 in the plan, so the error also comes from planning. Action: refuse any departure before 06:30, correct the plan, inform the focal point.
• Mike 2 announces on the radio that it is carrying 450,000 meticais (rule 6): anyone listening to the frequency knows that a vehicle is carrying money on this road. Action: interrupt the message, immediately inform the security focal point (the risk to this vehicle and to future cash transports must be reassessed), remind staff of the rule.
• Mike 1 picks up two unauthorised teachers (rule 5) and the operator replies "Copy that" instead of refusing. Action: the operator must refuse and the focal point is informed; the rule protects the team and perceived neutrality, and insurance does not cover unauthorised passengers.
• The operator mentions the names of the doctor and the project manager on the radio (rule 6) and announces their return "tonight". Action: use call signs or switch to the phone.
• Mike 3 does not call at P3 and goes more than 60 minutes without contact (rule 2), and the operator does not apply the overdue procedure (rule 4).

Example: "OVERDUE ALERT Mike 3 (AGZ 951 MP). Left Site Bravo 14:40, 3 passengers, returning to base via P3. Expected at P3 at 15:28, no call. Last contact 14:40. Attempts since 15:58: radio, driver's phone, phones of the 2 reachable passengers, satellite phone: no answer. Expected arrival at base 16:10. Awaiting your instructions; I am continuing calls every 5 minutes."

"Alpha Hotel Golf, Tree Wun Fower, Mike Papa". In radio procedure, digits are pronounced in the ICAO way ("Tree", "Wun", "Fower") so they are clearly understood. Say "I spell" before spelling.
