Binbrook Minival-inject suspect package with aid of (real) Postman Pat. Uneven weight, grease stains, wires. At each stage it is re-injected it is dealt with properly and promptly. Then we get it into the COC. "That for me?" asks the Staish (it was addressed to him by name). He takes it and pulls dinghy knife - "Could you hang on please sir. We'd like all the execs to see it." " No" says Staish, it is addressed to me. Before we can say or do anything he slits seal with dinghy knife. Package bursts into flames (no explosive just an ignition device). Staish incandescent, us on Distaff trying not to laugh, and wondering how we will write up the post exercise comment.
