Although they offer advantages, there is one big disadvantage: drag. That's something that they endeavor to reduce as low as possible as it has a major impact on speed and fuel economy. -----Original Message----- From: Lluis Ripoll Sent: Monday, July 23, 2012 6:56 AM To: Leica Users Group Subject: Re: [Leica] IMG: Airport Snaps Jim, Nice shots and interesting details for those who doesn't know such techniques cheers Lluis El 20/07/2012, a las 22:01, Jim Nichols escribi?: > A lot of general aviation flights rely on the principle of "see and be > seen" to avoid conflicts, particularly around airports.
