With continued fall, the lower edge of a blood drop may slightly flatten. The interpretation as an elongated shape may be based on photographs from the side showing contact and continued flow on a slant or the lack of speed in capturing the drop in free fall. What is essentially important in determining drop shape in flight is the initial footprint on contact.

The internal cohesion created by red blood cells forms a much stronger bond to keep the blood drops in a tight spherical shape compared to the surface tension of water.  INTRODUCTION 2. 4 Water drops distortions in flight. 5 Blood drops from injury to the mouth (see also the cover photo of this book).
