While she was in Nairobi, Mary Heath asked a local garage to remake her Avro Avian’s undercarriage and repair the petrol tank. She was annoyed to find that few of the telegrams she had sent to let the authorities know where she was ever delivered - yet she still got the blame for communication problems.
‘Owing to her slackness in letting us know her movements, we are unable to keep pace with the vagaries of Lady Heath,’ one official file stated.
This seems unfair; copies of telegrams she sent while in Nairobi to the authorities in Khartoum and Cairo as well as in Kisumu and Entebbe still exist.
After about a week, she was off again, still with the Bentleys in tow. With the Avian heavily loaded, it took nearly 250 metres for the craft to become airborne, the longest run yet. Ahead was the 3,000 metre Kijabe escarpment, an intimidating height for a small and overloaded plane. After a fruitless attempt to gain altitude, Lady Mary decided to make an 80 kilometre detour, following the railway line in hopes of finding an easier way over the top. Even when she did, she scraped over the hills by a mere six metres after lightening her load by throwing overboard her tennis racquet, some books and a pair of shoes.
