London, February 27 : British prince William may have to drink beer from loo, while his younger brother Harry faces a Naked Runway Challenge, as part of bizarre traditional initiation rituals at RAF bases.

According to reports, William may have to drink through a straw from a toilet filled with beer, as buckets of icy water are tipped over his head.

Harry, on the other hand, may have to strip off to run the length of the landing strip at RAF Barkston Heath in Lincolnshire.

The acts are said to be traditional rituals at bases where the two princes are training to become helicopter pilots.

Wills is expected to undergo his initiation next month, when he joins his new training squadron at RAF Shawbury, Shrops.

"No one is forced to take part but I don't know a single person who has chickened out. I'm sure William will be keen to prove he is one of the boys," the Sun quoted an RAF source as saying.

"Harry's test will be different. The runway is long, and freezing at this time of year. It's always a relief when you have passed the initiation and earned your drinking wings," the source added. (ANI)
