I remember OC92 leading us on a night 4-ship Victor AAR in the 80s; 'twas a v dark night and he had trouble getting visual with the tanker as we rolled in behind in trail at about a mile. He asked the tanker to check his lights were on full brightness. The tanker obliged by firing a white Verey......cue much swearing as all 8 of us lost our night vision for about 10 min......
