Approaching Cairo one rather poor weather day, we were turned onto the 23L ILS and cleared for approach, only to find that the ILS tripped off, the VOR went away, and all comms with approach control/tower seemed failed as well.
A JCB had just sliced through a big electrical cable, I was told later.
The Honeywell HT9100 GPS (dual installation, L1011 aircraft) found the runway quite nicely, so I called Cairo ground, and requested landing clearance.
A very weak ground, from an emergency vehicle, replied....LN202, 23R, cleared to land.
The approach clearance was for the 23L ILS, however, the proceeding aircraft, who had landed on 23L had two deflated tires, and still occupied the runway...and with 800 meters vis, I hardly think we would have seen him for adequate separation.
Land without a clearance...sometimes expect rather large problems.
Them's the facts.
